Kinematic Problem Solving Techniques

This video tutorial teaches how to create and use a kinematics equation chart to solve problems. It covers the five kinematic variables and four key equations, explaining how to identify which equation to use based on given and unknown variables. An example problem is solved using the chart, demonstrating the process of selecting the appropriate equation and performing calculations.

What is the primary purpose of creating a kinematics equation chart?

• To calculate the speed of light

• To solve algebraic equations

• To determine which equation to use for a specific problem

• To memorize all kinematic equations

Which of the following is NOT a kinematic variable?

• Mass

• Initial velocity

• Displacement

• Acceleration

Which kinematic equation does NOT include displacement?

• Delta X = 1/2 * (VI + VF) * t

• VF = VI + a * t

• Delta X = VI * t + 1/2 * a * t^2

• VF^2 = VI^2 + 2 * a * Delta X

In the second kinematic equation, which variable is missing?

• Acceleration

• Final velocity

• Initial velocity

• Time

What should you do first when solving a kinematic problem?

• Calculate the final velocity

• Write down the given and unknown variables

• Guess the answer

• Draw a diagram

If a problem does not provide or require the final velocity, which equation should you use?

• VF^2 = VI^2 + 2 * a * Delta X

• Delta X = VI * t + 1/2 * a * t^2

• Delta X = 1/2 * (VI + VF) * t

• VF = VI + a * t

• 4 m/s^2

• 5 m/s^2

What is the calculated displacement of the car in the sample problem?

• 50 m

• 62.5 m

• 75 m

• 100 m
