Question

A ball is thrown up into the air. Explain what happens to its potential and kinetic energies as it moves up and then back down

Answer 1

KE=kinetic energy, PE = potential energy

when the ball is moving up, the ball gain PE and lose KE

when the ball reaches its maximum height, PE is MAX and KE is zero

when the ball is falling down, PE of ball start to lose gradually and the KE will increase
