Let a body of mass m lying at position A at a height h above the ground. As the body falls, its Kinetic Energy increases at the expense of potential energy.

At Point A
The body is at rest

At Point B
Let the body falls freely through height x and reaches the point B with velocity v, then

At Point C
Let the body finally at point C on the ground with velocity v’, then considering Motion from A to C.

Clearly, As the body falls, Its Potential Energy decreases and Kinetic Energy increases by an equal amount. However the total Mechanical Energy remains constant at all points.
Given below are the graph represent the above situation.
