Question

Summary of a trade-off between. Potential and kinetic energy

Answer 1

Simply put, Potential energy is the "build up". If I had a ball on the top a 5ft slide, it would have potential energy, as long as it hasn't slid down yet.

If I had another ball on a 10ft slide, it would have twice the potential energy the first ball had.

What comes next is kinetic energy, which is the energy used when the object is moving, like the ball as it goes down the slide. The faster it moves, the more kinetic energy. 

Basically, Potential is the "build up" but it does not, I repeat does not move.

Kinetic energy is the use of the "build up" through movement.
