Question

Derive the formula of both kinetic and potential energy.

Answer 1

Answer:

Let the work done on the object against gravity =w

work done:w=mg×h

mgh

this is the potential energy ( Ep) object

Ep = mgh

Answer 2

Kinetic Energy:-

v ^ 2 - u ^ 2 = 2as… This statement states that a work W is done by a body to move from one position to another by a distance s when the force F is applied to a body at rest. This work done on the body is because of Kinetic energy (K.E) of the body.

Potential Energy:-

Expression for Gravitational Potential Energy at Height (h) – Derive ΔU = mgh. When, h<<R, then, R + h = R and g = GM/R2.
