- Where does gravity get its energy from? 8 answers
I have read many answers here about gravitational potential energy. Suppose that I am holding a ball 5 meters from the ground and I release it and it falls to the ground. Now i get that it falls because I did work against gravity to lift that ball to the height of 5 meters. But my question is that why did I have to do work against gravity? I mean where does gravity get the energy to pull the ball so that I have to do work to lift it? I hope you get my question.
