Stores.

Thermal, kinetic, gravitational potential, elastic potential, chemical, magnetic, electrostatic, nuclear.

How is energy transferred? (4)

Mechanically (force doing work), heating, electrically (moving charges), radiation (e.g. light/sound).

What happens when a system changes?

Energy is transferred (into or away from the system, between different objects in the system, or between different energy stores).

Closed systems.

Where no energy can enter or escape. The net change is always 0.

What is work done another way of saying?

Energy transferred.
