Question

If an object has 100 J of PE, how much work can it do (with that PE)?

Answer 1

Answer:

W = 100 J

Explanation:

The potential energy of an object is given by :

$P=mgh$

It is said to possessed by an object due to its position under the action of gravity.

The work done by an object is given by :

W = F×d , F is force and d is displacement

We know that, F = mg

So, if an object has 100 J of PE, it means that it can do the work of 100 J.
