v = 0 m/s
a = - 8.00 m/s
The next step of the strategy involves identifying a kinematic equation that would allow you to determine the unknown quantity. There are four kinematic equations to choose from. In general, you will always choose the equation that contains the three known and the one unknown variable. In this specific case, the three known variables and the one unknown variable are v f , v i , a , and d . Thus, you will look for an equation that has these four variables listed in it. An inspection of the four equations above reveals that the equation on the top right contains all four variables.
Once the equation is identified and written down, the next step of the strategy involves substituting known values into the equation and using proper algebraic steps to solve for the unknown information. This step is shown below.
(0 m/s) 2 = (30.0 m/s) 2 + 2 • (-8.00 m/s 2 ) • d
0 m 2 /s 2 = 900 m 2 /s 2 + (-16.0 m/s 2 ) • d
(16.0 m/s 2 ) • d = 900 m 2 /s 2 - 0 m 2 /s 2
(16.0 m/s 2 )*d = 900 m 2 /s 2
d = (900 m 2 /s 2 )/ (16.0 m/s 2 )
The solution above reveals that the car will skid a distance of 56.3 meters. (Note that this value is rounded to the third digit.)
The last step of the problem-solving strategy involves checking the answer to assure that it is both reasonable and accurate. The value seems reasonable enough. It takes a car a considerable distance to skid from 30.0 m/s (approximately 65 mi/hr) to a stop. The calculated distance is approximately one-half a football field, making this a very reasonable skidding distance. Checking for accuracy involves substituting the calculated value back into the equation for displacement and insuring that the left side of the equation is equal to the right side of the equation. Indeed it is!
Ben Rushin is waiting at a stoplight. When it finally turns green, Ben accelerated from rest at a rate of a 6.00 m/s 2 for a time of 4.10 seconds. Determine the displacement of Ben's car during this time period.
Once more, the solution to this problem begins by the construction of an informative diagram of the physical situation. This is shown below. The second step of the strategy involves the identification and listing of known information in variable form. Note that the v i value can be inferred to be 0 m/s since Ben's car is initially at rest. The acceleration ( a ) of the car is 6.00 m/s 2 . And the time ( t ) is given as 4.10 s. The next step of the strategy involves the listing of the unknown (or desired) information in variable form. In this case, the problem requests information about the displacement of the car. So d is the unknown information. The results of the first three steps are shown in the table below.
Diagram: | Given: | Find: |
---|---|---|
v = 0 m/s t = 4.10 s a = 6.00 m/s | d = ?? |
The next step of the strategy involves identifying a kinematic equation that would allow you to determine the unknown quantity. There are four kinematic equations to choose from. Again, you will always search for an equation that contains the three known variables and the one unknown variable. In this specific case, the three known variables and the one unknown variable are t, v i , a, and d. An inspection of the four equations above reveals that the equation on the top left contains all four variables.
d = (0 m/s) • (4.1 s) + ½ • (6.00 m/s 2 ) • (4.10 s) 2
d = (0 m) + ½ • (6.00 m/s 2 ) • (16.81 s 2 )
d = 0 m + 50.43 m
The solution above reveals that the car will travel a distance of 50.4 meters. (Note that this value is rounded to the third digit.)
The last step of the problem-solving strategy involves checking the answer to assure that it is both reasonable and accurate. The value seems reasonable enough. A car with an acceleration of 6.00 m/s/s will reach a speed of approximately 24 m/s (approximately 50 mi/hr) in 4.10 s. The distance over which such a car would be displaced during this time period would be approximately one-half a football field, making this a very reasonable distance. Checking for accuracy involves substituting the calculated value back into the equation for displacement and insuring that the left side of the equation is equal to the right side of the equation. Indeed it is!
The two example problems above illustrate how the kinematic equations can be combined with a simple problem-solving strategy to predict unknown motion parameters for a moving object. Provided that three motion parameters are known, any of the remaining values can be determined. In the next part of Lesson 6 , we will see how this strategy can be applied to free fall situations. Or if interested, you can try some practice problems and check your answer against the given solutions.

Problem-solving skills are obviously essential to success in a quantitative course in physics. More importantly, the ability to apply broad physical principles, usually represented by equations, to specific situations is a very powerful form of knowledge. It is much more powerful than memorizing a list of facts. Analytical skills and problem-solving abilities can be applied to new situations, whereas a list of facts cannot be made long enough to contain every possible circumstance. Such analytical skills are useful both for solving problems in this text and for applying physics in everyday and professional life.
While there is no simple step-by-step method that works for every problem, the following general procedures facilitate problem solving and make it more meaningful. A certain amount of creativity and insight is required as well.
Examine the situation to determine which physical principles are involved . It often helps to draw a simple sketch at the outset. You will also need to decide which direction is positive and note that on your sketch. Once you have identified the physical principles, it is much easier to find and apply the equations representing those principles. Although finding the correct equation is essential, keep in mind that equations represent physical principles, laws of nature, and relationships among physical quantities. Without a conceptual understanding of a problem, a numerical solution is meaningless.
Make a list of what is given or can be inferred from the problem as stated (identify the knowns) . Many problems are stated very succinctly and require some inspection to determine what is known. A sketch can also be very useful at this point. Formally identifying the knowns is of particular importance in applying physics to real-world situations. Remember, “stopped” means velocity is zero, and we often can take initial time and position as zero.
Identify exactly what needs to be determined in the problem (identify the unknowns) . In complex problems, especially, it is not always obvious what needs to be found or in what sequence. Making a list can help.
Find an equation or set of equations that can help you solve the problem . Your list of knowns and unknowns can help here. It is easiest if you can find equations that contain only one unknown—that is, all of the other variables are known, so you can easily solve for the unknown. If the equation contains more than one unknown, then an additional equation is needed to solve the problem. In some problems, several unknowns must be determined to get at the one needed most. In such problems it is especially important to keep physical principles in mind to avoid going astray in a sea of equations. You may have to use two (or more) different equations to get the final answer.
Substitute the knowns along with their units into the appropriate equation, and obtain numerical solutions complete with units . This step produces the numerical answer; it also provides a check on units that can help you find errors. If the units of the answer are incorrect, then an error has been made. However, be warned that correct units do not guarantee that the numerical part of the answer is also correct.
Check the answer to see if it is reasonable: Does it make sense? This final step is extremely important—the goal of physics is to accurately describe nature. To see if the answer is reasonable, check both its magnitude and its sign, in addition to its units. Your judgment will improve as you solve more and more physics problems, and it will become possible for you to make finer and finer judgments regarding whether nature is adequately described by the answer to a problem. This step brings the problem back to its conceptual meaning. If you can judge whether the answer is reasonable, you have a deeper understanding of physics than just being able to mechanically solve a problem.
When solving problems, we often perform these steps in different order, and we also tend to do several steps simultaneously. There is no rigid procedure that will work every time. Creativity and insight grow with experience, and the basics of problem solving become almost automatic. One way to get practice is to work out the text’s examples for yourself as you read. Another is to work as many end-of-section problems as possible, starting with the easiest to build confidence and progressing to the more difficult. Once you become involved in physics, you will see it all around you, and you can begin to apply it to situations you encounter outside the classroom, just as is done in many of the applications in this text.
Physics must describe nature accurately. Some problems have results that are unreasonable because one premise is unreasonable or because certain premises are inconsistent with one another. The physical principle applied correctly then produces an unreasonable result. For example, if a person starting a foot race accelerates at 0.40 m/s 2 for 100 s, his final speed will be 40 m/s (about 150 km/h)—clearly unreasonable because the time of 100 s is an unreasonable premise. The physics is correct in a sense, but there is more to describing nature than just manipulating equations correctly. Checking the result of a problem to see if it is reasonable does more than help uncover errors in problem solving—it also builds intuition in judging whether nature is being accurately described.
Use the following strategies to determine whether an answer is reasonable and, if it is not, to determine what is the cause.
Solve the problem using strategies as outlined and in the format followed in the worked examples in the text . In the example given in the preceding paragraph, you would identify the givens as the acceleration and time and use the equation below to find the unknown final velocity. That is,
Check to see if the answer is reasonable . Is it too large or too small, or does it have the wrong sign, improper units, …? In this case, you may need to convert meters per second into a more familiar unit, such as miles per hour.
This velocity is about four times greater than a person can run—so it is too large.
If the answer is unreasonable, look for what specifically could cause the identified difficulty . In the example of the runner, there are only two assumptions that are suspect. The acceleration could be too great or the time too long. First look at the acceleration and think about what the number means. If someone accelerates at 0.40 m/s 2 , their velocity is increasing by 0.4 m/s each second. Does this seem reasonable? If so, the time must be too long. It is not possible for someone to accelerate at a constant rate of 0.40 m/s 2 for 100 s (almost two minutes).
The six basic problem solving steps for physics are:
1. What information do you need in order to choose which equation or equations to use to solve a problem? Explain. 2. What is the last thing you should do when solving a problem? Explain.

Fundamental physics—let alone quantum physics—might sound complicated to many, but it can actually be applied to solve everyday problems.
Imagine navigating to an unfamiliar place. Most people would suggest using GPS, but what if you were stuck in an underground tunnel where radio signals from satellites were not able to penetrate? That's where quantum sensing tools come in.
USC Viterbi Information Sciences Institute researchers Jonathan Habif and Justin Brown, both from ISI's new Laboratory for Quantum-Limited Information, are working at making sensing instruments like atomic accelerometers smaller and more accurate so they can be used to navigate when GPS is down.
Atoms are excellent at making accurate measurements because they are all the same. Atomic measurements made in one laboratory would be indistinguishable from those made in another laboratory, as the atoms behave in precisely the same way.
One example of how this physics concept can be applied is making a highly accurate navigation system with these atoms.
"As an atomic physicist, I work with atoms in a gas and talk to the atoms with lasers," Brown said. "As atoms have mass, they can be used to measure accelerations, helping us build atom-based sensors like atomic accelerometers."
Habif added, "The accelerometers let you know how fast and far you're moving in a given direction. They can be coupled with gyroscopes, which tell you whether you've changed directions and how far you've turned, to make a complete measurement. These navigation instruments are useful when you don't have access to GPS."
One of the challenges they're facing is how they can engineer this in a thoughtful way.
For example, they have to think very carefully about how they can miniaturize atomic accelerometers. These accelerometers have historically operated in big laboratory scale systems, where equipment is heavy and consumes a lot of power. To make the accelerometers suitable for public use, Habif and Brown are investigating how to retain their high precision in a much more compact, power-efficient and attractive medium.
Brown said, "We want to take this out in the field and make it smaller at the same time, but the techniques and supplies that we're drawing from are not very conducive to doing so just yet. I'm thinking about how to talk to the atoms in a different way so that we can get the capabilities to apply it to problems outside the laboratory."
Not only do quantum sensing devices work in areas that don't have access to GPS, they can also be part of an exciting new avenue: national security applications.
"Modern conflicts are becoming increasingly electronic and less kinetic, as nations vie for information superiority. The radio signal from GPS satellites is easy to disrupt and jam because it is far away. Thus, in any modern conflict, both sides will attempt to deny each other access to these radio signals ," Brown said.
"More traditional navigation instruments like inertial systems are un-jammable, as they work by adding up accelerations and rotations to measure our change in position. So they can replace GPS in times of conflict. However, all the errors made also get added up, so we are interested in using an atom-based measurement to ensure it is more accurate."
Atomic accelerometers are one example of these inertial systems. These systems are present in sensors on aircraft and ships, guiding their movement through airspaces and waters. However, existing mechanical-based sensors can wear out easily due to friction, leading to them being swapped out every year and costing a lot of money. They are also hard to build because they're small and delicate.
The US Department of Defense (DoD) is looking for upgrades in their inertial systems so that these difficulties can be overcome. The quantum approach based on atoms pursued by Brown and other groups could provide acceleration measurements with no moving parts.
"For example, if submarines want to be stealthy and quiet in defense scenarios, keeping track of what it's doing and how it's moved through inertial systems is pretty much the only game in town. I'm developing ideas on improving these systems for the DoD, so that they can be downsized and more cost-efficient," noted Brown.
Brown maintains that quantum sensing will be important on many fronts.
"Preparing for technical surprise means preparing for when GPS fails—the question isn't if GPS fails," said Brown. "It's very easy to stop GPS from working, so inertial sensors will always be useful. But it's still vital for us to solve the size issue, because a lot of these sensors still end up at about the size of a washing machine. I could simplify the tool itself, but I still need to make a good measurement."
Achieving this fine balance between simplicity and accuracy is the researchers' main goal, and they hope that their efforts will translate to real-world prototypes someday.

Stumped five ways to hone your problem-solving skills.
Respect the worth of other people's insights
Problems continuously arise in organizational life, making problem-solving an essential skill for leaders. Leaders who are good at tackling conundrums are likely to be more effective at overcoming obstacles and guiding their teams to achieve their goals. So, what’s the secret to better problem-solving skills?
“Too often, people fail because they haven’t correctly defined what the problem is,” says David Ross, an international strategist, founder of consultancy Phoenix Strategic Management and author of Confronting the Storm: Regenerating Leadership and Hope in the Age of Uncertainty .
Ross explains that as teams grapple with “wicked” problems – those where there can be several root causes for why a problem exists – there can often be disagreement on the initial assumptions made. As a result, their chances of successfully solving the problem are low.
“Before commencing the process of solving the problem, it is worthwhile identifying who your key stakeholders are and talking to them about the issue,” Ross recommends. “Who could be affected by the issue? What is the problem – and why? How are people affected?”
He argues that if leaders treat people with dignity, respecting the worth of their insights, they are more likely to successfully solve problems.
Best 5% interest savings accounts of 2024, 2. unfocus the mind.
“To solve problems, we need to commit to making time to face a problem in its full complexity, which also requires that we take back control of our thinking,” says Chris Griffiths, an expert on creativity and innovative thinking skills, founder and CEO of software provider OpenGenius, and co-author of The Focus Fix: Finding Clarity, Creativity and Resilience in an Overwhelming World .
To do this, it’s necessary to harness the power of the unfocused mind, according to Griffiths. “It might sound oxymoronic, but just like our devices, our brain needs time to recharge,” he says. “ A plethora of research has shown that daydreaming allows us to make creative connections and see abstract solutions that are not obvious when we’re engaged in direct work.”
To make use of the unfocused mind in problem solving, you must begin by getting to know the problem from all angles. “At this stage, don’t worry about actually solving the problem,” says Griffiths. “You’re simply giving your subconscious mind the information it needs to get creative with when you zone out. From here, pick a monotonous or rhythmic activity that will help you to activate the daydreaming state – that might be a walk, some doodling, or even some chores.”
Do this regularly, argues Griffiths, and you’ll soon find that flashes of inspiration and novel solutions naturally present themselves while you’re ostensibly thinking of other things. He says: “By allowing you to access the fullest creative potential of your own brain, daydreaming acts as a skeleton key for a wide range of problems.”
“Admitting to not knowing the future takes courage,” says Professor Stephen Wyatt, founder and lead consultant at consultancy Corporate Rebirth and author of Antidote to the Crisis of Leadership: Opportunity in Complexity . “Leaders are worried our teams won’t respect us and our boards will lose faith in us, but what doesn’t work is drawing up plans and forecasts and holding yourself or others rigidly to them.”
Wyatt advises leaders to heighten their situational awareness – to look broadly, integrate more perspectives and be able to connect the dots. “We need to be comfortable in making judgment calls as the future is unknown,” he says. “There is no data on it. But equally, very few initiatives cannot be adjusted, refined or reviewed while in motion.”
Leaders need to stay vigilant, according to Wyatt, create the capacity of the enterprise to adapt and maintain the support of stakeholders. “The concept of the infallible leader needs to be updated,” he concludes.
“Organisations, and arguably society more widely, are obsessed with problems and the notion of problems,” says Steve Hearsum, founder of organizational change consultancy Edge + Stretch and author of No Silver Bullet: Bursting the Bubble of the Organisational Quick Fix .
Hearsum argues that this tendency is complicated by the myth of fixability, namely the idea that all problems, however complex, have a solution. “Our need for certainty, to minimize and dampen the anxiety of ‘not knowing,’ leads us to oversimplify and ignore or filter out anything that challenges the idea that there is a solution,” he says.
Leaders need to shift their mindset to cultivate their comfort with not knowing and couple that with being OK with being wrong, sometimes, notes Hearsum. He adds: “That means developing reflexivity to understand your own beliefs and judgments, and what influences these, asking questions and experimenting.”
Leaders must be able to communicate problems in order to find solutions to them. But they should avoid bombarding their teams with complex, technical details since these can overwhelm their people’s cognitive load, says Dr Jessica Barker MBE , author of Hacked: The Secrets Behind Cyber Attacks .
Instead, she recommends that leaders frame their messages in ways that cut through jargon and ensure that their advice is relevant, accessible and actionable. “An essential leadership skill for this is empathy,” Barker explains. “When you’re trying to build a positive culture, it is crucial to understand why people are not practicing the behaviors you want rather than trying to force that behavioral change with fear, uncertainty and doubt.”

America has a physics problem.
Research shows that access to physics education varies based on race, gender, sexuality and disability . Physics courses are usually standard offerings in suburban high schools, but at urban and rural schools that isn’t the case .
Even in places where physics is taught, the lessons rarely highlight how physics can be applied to students’ everyday lives.
This approach can hamper students’ desire to learn . In my work as a physics education researcher , I’ve encountered lessons centered on the rote memorization of formulas. This method fails to encourage critical thinking, constraining students’ ability to creatively solve problems.
Teachers sometimes believe that if a student can’t grasp a physics concept, it’s the student’s problem. Instructors oftentimes don’t try to present the materials in a way that could help students engage more deeply with the lessons. This adds to the challenges poorer, nonwhite students already face, which include being held to lower standards and having fewer classroom resources .
Imagine if, instead, students could see how physics influences their daily lives in sports, extreme weather or baking and cooking. How might these real-world connections spark curiosity and foster a deeper understanding of physics?
Not adequately teaching physics has consequences.
As the economy becomes more tech-centered , understanding physics is critical. Yet the number of Americans with a solid grasp of physics is dwindling .
If there’s a shortage of candidates for jobs requiring a basic understanding of physics, it could hurt the ability of the U.S. to compete in the global economy, or it could compel companies to outsource certain jobs to countries with a better-educated workforce.
Many students have a vague notion that they would like to pursue STEM careers; they realize that these jobs usually pay well and can be interesting and fulfilling. But they aren’t even aware that learning physics can better prepare you for a role as an aerospace engineer, software developer or environmental scientist, to name just a few.
Understanding that relationship alone could boost their desire to learn the material.
But there’s another way to boost motivation, which I’ve spent years studying and developing , called “culturally relevant physics education.”
Physics is usually taught in ways that don’t connect with a diverse student body, leading to lower performance and engagement, especially among poor and nonwhite students. This can cause these populations to see little value in learning physics .
A traditional high school physics class teaches abstract equations and focuses on topics such as projectile motion and electrical circuits. The teacher might explain Newton’s laws of motion using examples exclusively from European history, such as the firing of cannonballs .
I wouldn’t fault students in, say, Raymond, Mississippi, for wondering why in the world they’re learning about the trajectory of 18th-century weaponry.
By shifting to teaching physics in culturally responsive ways, I believe it’s possible to reverse this trend and cultivate a new generation of physics enthusiasts and professionals. There are plenty of ways to do this.
I’ve worked with teachers in California to explore how the physics of wave motion affects earthquake dynamics and how buildings are constructed. Other lessons include understanding how text messages are transmitted through wave motion and how the physics of firearms can be taught using the concepts of the conservation of momentum and impulse .
In these ways, teachers can tap into students’ cultures and interests to make physics more relatable and engaging. There is no one-size-fits-all approach: While the physics of earthquakes might resonate better in one region’s school district, the physics of hurricanes might work better in another.
The rural South, in particular, has an acute need for more opportunities to learn physics.
Data from the National Center for Education Statistics indicates that students in these areas have less access to advanced science courses , including physics, than their urban and suburban counterparts. And a 2021 report by the American Institute of Physics notes that fewer high schools in the rural South offer Advanced Placement physics courses, which could be due, in part, to the significant shortage of qualified physics teachers in these communities.
Targeted interventions could help meet this need.
I’ve already collaborated with teachers in the Southeast to develop activities using NASCAR – a hugely popular sport in the region – so students can learn about engine types, acceleration and thermal energy. I’m also one of the principal investigators in a collaboration between Michigan State University and two HBCUs, Alabama A&M University and Winston-Salem State University , to implement culturally responsive physics education in the rural South .
Given the region’s rich agricultural history , the science of raising plants and crops can be another avenue for physics instruction. Teachers could detail how light energy is converted into chemical energy; explain how fruits and vegetables have unique colors due to the ways they absorb and reflect wavelengths of light; and relate how physics concepts such as fluid dynamics can be used to improve irrigation techniques.
By learning these real-world applications, students from agricultural areas could become empowered to contribute to their communities.
This project is not just about filling a gap in physics instruction; it’s also about unlocking the potential of students in the rural South. And we hope they’ll eventually feel confident enough about their physics backgrounds to one day pursue careers in STEM.

Calm down. It is just a problem, not the end of the world! 2. Read through the problem once. If it is a long problem, read and understand it in parts till you get even a slight understanding of what is going on. 3. Draw a diagram. It cannot be emphasized enough how much easier a problem will be once it is drawn out.

In force problems, isolate the appropriate components of the system and sketch a force diagram for them. Put a coordinate system on each diagram. Deduce the appropriate equations of motion. In other problems, cite the appropriate laws and relations, and justify the equations you deduce where necessary. Be certain that all symbols you use have ...
d = vi • t + ½ • a • t2. Once the equation is identified and written down, the next step of the strategy involves substituting known values into the equation and using proper algebraic steps to solve for the unknown information. This step is shown below. d = (0 m/s) • (4.1 s) + ½ • (6.00 m/s 2) • (4.10 s) 2.
