Question

What is potential energy?derive an expression for gravitational potential energy???​

Answer 1

Answer:

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

Answer 2

Answer:

• Potential energy, stored energy that depends upon the relative position of various parts of a system. A spring has more potential energy when it is compressed or stretched. A steel ball has more potential energy raised above the ground than it has after falling to Earth.
• Expression for Gravitational Potential Energy at Height (h) – Derive ΔU = mgh. When, h<<R, then, R + h = R and g = GM/R2. ⇒ Note: The weight of a body at the centre of the earth is zero due to the fact that the value of g at the centre of the earth is zero.
