Question

the potential energy of a free falling object decreases progressively what happened to it's a)kinetic energy b) total mechanical energy. state the law on which your answer is based​

Answer 1

Answer:

The potential energy is decrease as the height of the body from the earth surface is decreases.

While the kinetic energy increase as object falling down.

Kinetic energy is the energy in motion while potential energy is the energy at rest in the object.

The total mechanical energy is equal to total kinetic energy and total potential energy

Hence if kinetic energy increase potential energy decrease or vise versa.

On the basis of formula of potential energy it's prove because P.E. = mgh here as the height increase P.E. also increases and if P.E. increase obviously K.E. energy will decrease
