A child drops a ball. The ball hits the ground and bounces. The graph to the left shows the velocity-time graph for the ball from when the ball is dropped until when the ball reaches the top of its first bounce. Air resistance has been ignored. When the ball hits the ground, energy is transferred from the ball to the Earth. Explain how the data in the graph above shows this energy transfer.
