The velocity v against time t graphs for four objects A, B, C and D are shown below.

Which object travels the greatest distance between t = 0 and t = T?

The velocity-time graph of a car traveling in a straight line is shown below.

Which of the following is the best estimate for the distance travelled by the car?

The distance-time graph of a cyclist’s journey is shown below.

Which of the following statements are true?

1. The velocity of the cyclist at point A is 4.67 m s^-1

2. The velocity of the cyclist at point B is 3.75 m s^-1

3. The cyclist has constant velocity at point C

4. The cyclist has constant acceleration at point D

The graph below shows the motion of an object.

Between t = 0 s and t = 5 s, the acceleration is – 3 m s^-2.

By determining the scale of the y-axis, what is the velocity of the object at t = 8 s?

The graph below shows the velocity-time graph of a simple pendulum.

Which points on the graph lie at the point of greatest acceleration?

An object is travelling backwards in a straight line, with a constant speed of 2 m s^-1. At  t = 0 s, the displacement of the object is 3 m.

By taking forward motion as positive, which statement best describes the displacement-time graph of the object?

The diagram below shows a particle traveling clockwise in a circular path from point A to point B. The time taken is 6.5 s. The radius of the circle is 11 m.

What is the average speed of the particle?

A child on a swing is released from rest, x cm away from its equilibrium position.

Which graph describes the velocity of the swing?

A particle has a constant acceleration of - 4.4 m s^-2. At t = 0, the velocity u of this particle is 15 m s^-1.

What is the value of t when the velocity has halved?

Car X and Car Y have velocities of v_X and v_Y respectively. Car X takes three quarters of the time that Car Y takes to reach distance s.

What is the value of the ratio ?
