Question

what is potential energy with it's derivation​

Answer 1

Answer:

Potential Energy:

Potential energy is defined as mechanical energy, stored energy, or energy caused by its position. The energy that a ball has when perched at a top of a steep hill while it is about to roll down is an example of potential energy.

Derivation for the equation of Potential Energy:

Let the work done on the object against gravity = W

                Work done, W = force × displacement

                Work done, W  = mg × h

                Work done, W = mgh

Since work done on the object is equal to mgh, an energy equal  to mgh units is gained by the object . This is the potential energy (Ep) of the object.

                             Ep = mgh

Answer 2

Answer:

Potential energy for the gravitational force the formula us P.E.= mgh , where m is the mass in kilograms , g is the acceleration due to gravity ( 9.8m/s2 at the surface of the earth ) and h is the height in meters .

gravitational potential energy has the same units as kinetic energy , kg m2/s2
