the potential energy is a type of energy
example for potential energy
when we throw a ball we can calculate it's p.e by the formula of P.E = m×g×h
which is
m = mass
g = gravitational force
h = height
I hope this helps

-The energy of a body due to its position or change in shape is known as potential energy.
-The potential energy of a body is due to its higher position above the earth and its equal to the work done on the body, against gravity, in moving the body to that position.
-So, to find out the potential energy of a body lying at a certain height, all that we have to do is to find out the work done in taking the body to that height.
-Suppose a body of mass is raised to a height above the surface of the earth (see figure).
-The force acting on the body is the gravitational pull of the earth which acts in the downward direction.
-To lift the body above the surface of the earth, we have to do work against this force of gravity. Now,
So,
This work gets stored up in the body as potential energy. Thus,
Where,
= mass of the body
= acceleration due to gravity
= height of the body above the reference point, say the surface of earth
