Worked Solution & Example Answer:A child drops a ball - AQA - GCSE Physics - Question 1 - 2018 - Paper 1
Step 1
Describe the motion of the ball between points A and B on Figure 1.
Answer
The motion of the ball between points A and B is characterized by uniform acceleration. The graph shows that the velocity of the ball is increasing steadily as it falls, indicating that it is accelerating downwards under the influence of gravity.
Step 2
Step 3
Step 4
Explain how the data in Figure 1 shows this energy transfer.
Answer
The data in Figure 1 indicates that when the ball hits the ground, there is a transfer of energy from the ball to the Earth. This is shown by the decrease in velocity immediately after the ball impacts, which implies that kinetic energy is lost. Additionally, the height of the ball after the bounce is less than the height from which it was dropped, further indicating a reduction in energy, specifically kinetic energy, thus transferring energy to the Earth during the collision.
