"The speed of the car is decreasing."

Multiple Choice

Match the description to the graph:

"The car is traveling at a constant speed away from start."

Multiple Choice

In which of the following graphs below are both runners moving at the same speed?

Multiple Select

The distance-versus-time graph represents the motion of John and Peter in roller blades.

Which BEST describes the skaters' movement? Select ALL that apply.

• Peter is moving slower than John and in an opposite direction.

• John is moving faster than Peter and in the same direction.

• Both are moving at a constant speed and in the same direction.

• Both are moving at a constant speed and in opposite directions.

• John's speed is increasing, and Peter's speed is decreasing, while both move in the same direction.

Multiple Choice

The driver of a car completes a trip. The graph displays data about the car's motion during the trip.

Which of the following statements about the car's motion is true?

• The total time for the car trip was 50 minutes.

• The car returned to where it had started the trip at the end of the trip.

• The car did not slow down during the trip.

• The car did not travel at a constant speed during the entire trip.

Multiple Choice

What car has the fastest acceleration?

• Car goes from 0-60 Mph in 3 seconds

• Car goes from 0-60 Mph in 4 seconds

• Car goes from 0-60 Mph in 5 seconds

• Car goes from 0-60 Mph in 6 seconds

Multiple Choice

In each of the following cases, determine where the car has no acceleration ?

• A car shortly after a stoplight turns green.
• A car approaching a red light
• A car with the cruise control set at 80 km/h
• A car turning a curve at a constant speed

Multiple Choice

When a car goes around a corner at 20 mph, why do we say it accelerates?

• The car is accelerating because of the velocity is constant

• The car accelerates because it's going 20 mph

• Cars always accelerate when they are in motion

• The car is accelerating because it's changing direction

Multiple Choice

Mrs. Hayes kept a chart of the velocity and acceleration of her runners at the track meet last week.

Which of the following statements BEST explains the relationship between the acceleration and velocity of the runners?

• The runner with the lowest velocity at 20m will have the lowest acceleration.

• The runner with the highest velocity will always have the highest acceleration.

• The velocity of a runner can never increase when running an extended distance.

• The runner with the greatest change in velocity will have the highest acceleration.

Multiple Choice

A student is investigating mass and acceleration. The student applies the same force to two boxes, as shown in the table.

The student claims that box 1 must have a smaller mass than box 2. Which argument best supports the student's claim?

• Heavier objects require less force than lighter objects to accelerate at the same rate.

• Heavier objects require greater force than lighter objects to accelerate at the same rate.

• Lighter objects require less force than heavier objects to start moving but will accelerate at the same rate.

• Lighter objects require greater force than heavier objects to start moving but will accelerate at the same rate.

Multiple Choice

"If we apply a ___________ to an object, its __________________ will change and it will  ______________."

• force, accelerate, gravity
• accelerate, inertia, gravity
• force, velocity, accelerate
• velocity, gravity, inertia

Multiple Select

This object would be moving (pick all that are correct):

• up

• down

• left

• right

Multiple Choice

Whenever an object is moving, there is always this force opposing the motion:

• inertia

• momentum

• friction

• applied force

Multiple Choice

Examine the table provided. Which of the objects is producing the greatest force?

• Soccer Ball

• Tennis Ball

• Marble

• Ping-Pong Ball

Multiple Choice

The masses of four objects are given in this table. If all objects are struck with the same amount of force, which one will have the greatest acceleration?

• Object 1

• Object 2

• Object 3

• Object 4

Multiple Choice

In which scenario is the object in equilibrium?

• the book on the table

• the car gaining speed

• the rope being pulled

• the weight being lifted

Multiple Choice

Pamela rolled the ball into the grass. The ball slowed down and eventually came to a stop while rolling on the grass.

Which of the following BEST explains why the ball stopped rolling?

• The ball stopped rolling when it reached the grass because the force of friction acted on the ball causing it to stop moving.

• The ball stopped rolling when it reached the grass because the force of gravity acted on the ball causing the ball to stop moving.

• The ball stopped rolling when it reached the grass because the ball did not have enough acceleration to continue rolling in the grass.

• The ball stopped rolling when the force causing the ball to roll ran out, and there was no additional force applied to the ball to keep it in motion.
