Law of Conservation of Energy

It states that energy can neither be created nor destroyed, but it can be transformed from one form to another.

The total energy before and after the transformation remains the same.

potential energy + kinetic energy = constant

`"mgh" + 1/2"mv"^2 = "constant"`

The sum of kinetic energy and potential energy of an object is its total mechanical energy.
We find that during the free fall of the object, the decrease in potential energy, at any point in its path, appears as an equal amount of increase in kinetic energy. (Here the effect of air resistance on the motion of the object has been ignored.) There is thus a continual transformation of gravitational potential energy into kinetic energy.
