Law of conservation of energy states that energy cant be created and cant be destroyed. but it can only transform from its one form to another.

Potential energy + kinetic energy = constant

mgh + 1/2 mv2 = constant

Energy cant be created nor be destroye only it can be transformed..

Law of conservation of energy (during a free fall )

Let a object be 'm ' , lay on point 'a ' and is lifted to pt 'h ' and stopped at pt 'b '

therefore work done on the body is mgh.

as the body is at rest at 'b '

Kinetic energy at 'b ' = 0

Potential energy at 'b ' =mgh

Therefore total energy at 'b ' =mgh +0



the answer is really very long 

if u want it just inform me I 'll give.
