Question

A person throws a ball up into the air, and the ball falls back toward earth. At which point would the kinetic energy be the lowest

Answer 1

The kinetic energy of the ball would be the lowest at the highest point of its trajectory. This is because as the ball is thrown upwards, it gains potential energy due to its increasing height and loses kinetic energy. At the highest point, just before the ball starts falling back towards the Earth, its kinetic energy would be at its minimum.
