Question

When an object is lifted from the surface of the Earth, some force is applied and the stored energy is Potential Energy. Also, we know that PE = mgh.

Therefore, is it true that the force that is applied to lift that object SHOULDBE greater than mgh?

P.S. If Force

Also, if Force=mgh, they both cancel out each other and hence, the object remains stationary.

Solution

Potential Energy is given by mgh. While the force required to do the work in lifting the body is F = mg.
