Question

mathematical derivation of potential energy​

Answer 1

Explanation:

The formula for potential energy depends on the force acting on the two objects. For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters. Notice that gravitational potential energy has the same units as kinetic energy, kg m2 / s2. In fact, all energy has the same units, kg m2 / s2, and is measured using the unit Joule (J).

Answer 2

Answer:

Explanation:

Let us consider a body of mass m raised from the ground to the height h, the amount of work done against gravity is

W = F x h

But, F = mg, the weight of the body.

So, W = mgh
