A mango on the tree possesses potential energy when falling down potential energy, the potential energy is converted to kinetic energy. what is the value of potential energy at the point of the mango hangs on there.

Answer 1

m g h = potential energy at top
(1/2) m v^2 = kinetic energy at ground
so
potential energy at top = (1/2) m v^2
where v is the speed at the ground

Answer 2

What energy changes involves switching on torchlight
