when an apple falls from a tree what happens to its gravitational potential energy just as it reaches the ground?After it strikes the ground?

Its potential energy increases as it changed its position as we know potential energy is the energy where its positio is changed from high to low

Its potential energy changes to kinetic energy as when the apple fall it losses its energy as it increses when its raises up so now the apple is in motion so kinetic energy increases and potential energy decreases
