- Energy stores (8 must know)
- Kinetic - anything moving
- Energy transferred to this store if object speeds up & away from store if slows down
- Kinetic energy = 0.5 x mass x (speed)²
- KE = 1/2 x m x v²
- Thermal - any object, the hotter it is the more energy it has in it's store
- Chemical - anything that releases energy by chemical reaction
- Gravitational potential - anything in a gravitational field (anything that can fall)
- When object is at any height above Earth's surface it will have energy in its gravitational potential energy store
- Can calculate change in energy in gravitational potential energy store: GPE = m x g x h
- Elastic potential - anything stretched (springs, rubber bands)
- Electrostatic - 2 charges that attract or repel each other
- Magnetic - 2 magnets that attract or repel eachother
- Nuclear - atomic nuclei release energy from store in nuclear reactions
- Kinetic - anything moving
