Conversion Between Gravitational and Kinetic Energy

The Law of conservation of energy states that energy cannot be created or destroyed but can be transferred from one form to another and from one object to another either by heating or doing work.Energy can be transferred from kinetic energy to gravitational potential energy when an object is thrown upwards or raised or from gravitational potential energy to kinetic energy when an object is dropped.ΔE_p = E_k.Assuming there are no other energy transfers:mgΔh = ½ mv² .The masses cancel since both ΔE_p and E_k are dependent on mass.This means the speed at which an object dropped from rest hits the ground is dependent solely on its height above the ground.The speed v = √(2gΔh)
