AQA GCSE Velocity time graphs and acceleration(Physics)

Practice Questions

1.What information will the gradient of a velocity time graph give us?

Acceleration

2. How can you tell if the acceleration is uniform from a velocity time graph?

If the velocity time graph is a straight line, then the acceleration is uniform. Uniform acceleration means that the acceleration has a constant value

3. How could you identify if an object is not accelerating by examining the velocity time graph?

If the object is not accelerating, then the line on the velocity time graph will be horizontal, so the gradient is 0 and the acceleration is zero.

4. A ball is thrown upwards in the air, where it reaches a maximum height and then falls back to its original position. Use the velocity time graph below to answer the following questions.

Velocity time graph for a ball being thrown upwards and then falling back down to its original position

4a.Describe the motion of the ball between 0 to 0.5 seconds.

The ball is moving upwards with constant or uniform acceleration

4b.State the time when the ball reached its maximum height

The ball reached its maximum height when the velocity is 0m/s. The time at which this happened is approx 0.9 seconds.

4c.How long did it take for the ball to reach its original position?

Two seconds

4d.State the time period when the ball is falling.

Approx 0.9-2 seconds
