What is the Law of Conservation of Energy?

• Most forms of energy are eventually transformed into thermal energy

• Systems lose energy as heat

• Energy cannot be created or destroyed, only changed form

• A fire gives off heat as it burns

Most kinetic energy exchanges usually end with thermal energy. Does that mean the energy disappears?

• Yes, where could it possibly go next?

• Yes, all energy eventually disappears.

• No, as the vibrating molecules spread apart they become kinetic energy that could move again in the future.

• No, as the vibrating molecules spread apart they become potential energy that could move again in the future.
