Potential energy
Question:


 Every object in nature that located at certain height
and gravity  acting on it has potential energy. 
 We can calculate use the equation Up=m*g*h. 

The energy released when the object falls.

In elevating system we use weights that has approximately the same weight as the elevator that is connected to it by a cable around a pulley, (look at the sketch).

when the elevator is in the 3rd floor and the weights is in the 2ns floor, which of them has a higher potential energy?

The elevator


The weights
It's unknown.
Both have the same potential energy.
