Physics

To calculate the work done by gravity as the ball moves from the lowest point to the highest point of its motion, we need to determine the change in gravitational potential energy. Since the ball is moving vertically from the lowest point to the highest point of the swing, the work done by gravity is equal to the negative of the change in gravitational potential energy.

The change in gravitational potential energy () is given by:

Where:

is the mass of the ball,

is the acceleration due to gravity,
