Energy = something that makes something happen
Ears
Sound Energy
Sound Energy moves by vibrating air particles, energy moves from 1 particle to the next
Parts of Ear
-Ear Drum
-Hammer
-Cochlea
-Anvil
-Stirrup

Eardrum
Cochlea
Nerve/brain
Heat Energy
Conduction
when two objects at different temperatures are in contact with each other. Heat flows from the warmer to the cooler object until they are both at the same temperature because the vibrations in one particle moving to the next
Convection
movement of heat energy in a fluid from hot to cold and vise versa
Radiation
Feeling the heat moving from a source
Conductor
Something heat can pass through
Insulator
Something to trap the heat in
Food Energy (chemical potential)
volume x temperature change x 4.2 = energy in food
Active
instant
Heat
Sound
Light
Kinetic
Electrical
Pontential
stored
Chemical P
Gravitational P
Elastic P
Nuclear P
Magnetic P
Energy Transformation
-Energy "changed" into another
Law of energy conservation
Energy cannot be created or destroyed ONLY transformed into other kinds
Efficiency = Useful energy divided by total energy x 100%
Energy = Joules (J)
