Motion Graphs

The graph shows how the distance varies with time for A a person taking their dog for a walk. Which part of the graph, A, B, C or D shows them taking a break from the walk?

• A

• B

• C

• D

Velocity can be found from the

• area under a displacement-time graph

• area under a force-time graph

• gradient of a displacement-time graph

• gradient of an acceleration-time graph

Acceleration can be found from the

• area under a distance-time graph.

• area under a velocity-time graph.

• gradient of a distance-time graph.

• gradient of a velocity-time graph.

The velocity-time graph for an object is shown.

The initial acceleration of the object is

• 0.40 m s^-2

• 0.50 m s^-2

• 2.0 m s^-2

• 9.0 m s^-2

Look carefully at the graph again. The displacement of the object during the deceleration is

• 29 m

• -29 m

• 15 m

• -15 m

The graph shows how velocity varies with time for an object.

The total distance travelled by the object in 4 seconds is

• 20 m

• 40 m

• 60 m

• 80 m

Look at the graph again. The acceleration at 3 s is

• 10 m s^-2

• 7 m s^-2

• 5 m s^-2

• 0 m s^-2

Distance travelled can be found from the

• area under a velocity-time graph

• area under an acceleration-time graph

• gradient of a force-time graph

• gradient of a velocity-time graph

A ball is thrown straight up in the air and caught when it comes down. Which graph best shows the velocity of the ball from the moment it is released until just before it is caught?

• A

• B

• C

• D

This time, a ball is dropped to the ground and caught when it bounces up again. Which of the following graphs shows the velocity of the ball?
