Potential and Kinetic energy

The video tutorial explains the dynamics of a bouncing tennis ball, focusing on energy transformations. Initially, the ball is raised, storing potential energy. As it falls, this energy converts to kinetic energy. At the midpoint, potential and kinetic energies are equal. When the ball hits the ground, kinetic energy is at its peak. The tutorial uses a 10-joule example to illustrate energy calculations, showing that mechanical energy remains constant as potential and kinetic energies interchange.

How is the mechanical energy calculated at the midpoint of the ball's fall?

Summarize the conversion of energy that occurs as the ball bounces.
