Question

define gravitational potential derive its equation​

Answer 1

Explanation:

Expression for Gravitational Potential Energy at Height (h) – Derive ΔU = mgh. If a body is taken from the surface of the earth to a point at a height 'h' above the surface of the earth, then ri = R and rf = R + h then, ΔU = GMm [1/R – 1/(R+h)] ΔU = GMmh/R(R + h) When, h<<R, then, R + h = R and g = GM/R2.
