Which of these is the equation for work done?

A ball has a mass of 0.046 kg.

Calculate the change in gravitational potential energy when the ball is lifted through a vertical height of 2.05 m.

Explain why the ball does not bounce back to its starting height of 2.05 m.

A student plots a graph showing the height at the start and the maximum height reached after each bounce.

Figure 16 shows the student’s graph.
