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

W = 100 J

Explanation:

The potential energy of an object is given by :

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.          

explanation: in any substance/object, the particles inside it (atoms/molecules) constantly move in random directions and with random speeds (this motion is called brownian motion). as a result, the particles have some kinetic energy (which is proportional to the temperature of the substance).

explanation:

have a great day!
