law of conservation of energy
Energy is neither created nor destroyed. It just changes from one form to another. You always have the same amount of energy in a system. No more no less!
This means that kinetic energy can turn into potential energy which can turn into kinetic energy which can turn into potential energy which can turn into kinetic energy which can turn into potential energy which can turn into kinetic energy which can turn into potential energy…….. |
