ENERGY - something stored in an object for anything to happen
We need energy to live eg energy we get from food
Joule (J) = unit for measuring energy
kilojules (kJ) - unit for measuring energy in food
Energy pathways/carriers
Heating
Lighting
Forces
Electricity
Through wires
Sound
Kinetic Energy/Store - energy stored in moving things
Thermal Store - energy stored in hot objects
Renewable Energy - energy source that will never run out eg solar power
Solar, wind, tidal, wave, bio-fuels, geothermal, hydroelectricity
Don't produce harmful gases of cause global warming
more expensive than fossil fuels
not always available
Nuclear Fuel - from nuclear power stations that generate electricity. Uranium
Non-renewable Energy - energy source that will run out eg oil
Fossil Fuels - oil, coal and gas. Made from remains of dead animals and plants
Produce gases that cause global warming when burnt
Quite cheap to get
Bio-fuel - made from plants or animal poo
Gravitational potential store - energy stored objects moving to high places
Chemical Store - energy stored in chemicals eg in food, fuel and batteries
Transfer - when energy moved from 1 store to another
Nuclear/Atomic Store - Energy stored inside particles
Elastic Potential Store - Energy stored in objects that are stretched, twisted or squashed
Fuel = something that contains alot of energy in its chemical or nuclear store
We get energy for our bodies from food
