Nommez quelques objets qui stockent l'énergie.

Nombre algunos objetos que almacenen energía.

Notes, Chapter 5Energy: the ability to do work.

Kinetic Energy: the energy caused by motion.

Potential Energy: stored energy due to position (ex: a book hanging from a string).

- Elastic potential energy (ex: stretching a rubber band)

- Chemical potential energy: energy stored in chemical bonds.

-Gravitational potential energy: energy stored in objects due to position above Earth’s surface.

Notes, Chapter 5 & 10• Law of Conservation of Energy: Energy can

only be converted, NOT created or destroyed. The total amount of energy in the universe does not change.

• Wave: a repeating disturbance or movement that transfers energy through matter/space.

• Medium: the thing that a wave transfers energy through. It can be a solid, liquid, gas, plasma, or space (or a combo of these).
