Explain how the energy storage changes when a ball is thrown upwards.

When a ball is thrown upwards, its kinetic energy decreases as it rises, while its gravitational potential energy increases. At the highest point, the kinetic energy is at its minimum and the gravitational potential energy is at its maximum.

This answer effectively describes the energy transfer between kinetic and gravitational potential energy, demonstrating an understanding of energy changes in a physical system. The question assesses the student's ability to apply knowledge of energy stores in a practical scenario.
