Kinematic Equations Quiz

What is the primary purpose of kinematic equations in physics?

• To analyze chemical reactions

• To measure temperature changes

• To determine the relationship between velocity, acceleration, time, and displacement

• To calculate gravitational force

Which of the following is NOT a component of kinematic equations?

• Initial velocity

• Final velocity

• Mass

• Acceleration

What is the first step in solving a kinematic problem?

• Read the question carefully

• Calculate the final velocity

• Identify the equation to use

• Convert units

In a kinematic problem, what does the 'no' variable indicate?

• The variable with the highest value

• The variable that must be calculated first

• The variable that is not given or needed

• The variable that is always zero

If a bus decelerates from 9.0 m/s to 0.0 m/s in 1.5 seconds, what is its acceleration?

• -6.0 m/s²

• 0.5 m/s²

A cyclist is traveling at 13.5 m/s and decelerates at -0.5 m/s². How long will it take to stop?

• 54 seconds

• 13.5 seconds

• 6.75 seconds

What is the final velocity of a car that accelerates uniformly from rest to 23 km/h in 6.5 seconds?

• 6.39 m/s

• 23 m/s

• 10 m/s

• 5 m/s

How far does a car travel if it accelerates from 4.3 m/s at 3.0 m/s² for 5 seconds?

• 45 m

• 30 m

• 59 m

A boy sledding down a hill accelerates at 1.4 m/s² from rest. What is his speed after traveling 17.5 m?

• 7.0 m/s

• 5.0 m/s

• 10.0 m/s

Which equation is used to find displacement when acceleration is unknown?

• ΔX = 1/2(VI + VF)ΔT

• VF² = VI² + 2aΔX

• ΔX = VIΔT + 1/2aΔT²

• VF = VI + aΔT
