You GOT THIS

Chemical energy

Chemical energy

turning one thing into a new thing by breaking down compounds- burning, eating food

Electrical energy

looking for electricity- lightning, anything plugged in outlet

mechanical energy

looking for physical movement- turning a wheel, running

nuclear energy

energy stored inside of atoms- nuclear fusion in sun, (nuclear bomb) nuclear fission

light energy

look for light- sun, anything that makes light

thermal energy

look for heat- fire, anything that gives off heat

sound energy

listen for sound- drums, anything that gives off heat

natural gas/oil

type of fossil fuel- obtained by drilling wells and fracking

fracking

water, sand, chemicals are pushed into the well and oil and gas come out

coal

types of fossil fuel- obtained by mining

nuclear energy

energy is used to heat water and spin turbines to generate energy (through generator)- energy obtained by splitting uranium atoms in nuclear powerplant

solar

sun- obtained by solar panels

wind

moving air- wind turbines, turbines move which generates electricity

geothermal

hot water in earth- geothermal powerplants hot water is brought up, which creates steam that turns turbines and generates electricity

biomass

burning organic material (trees)- water heated to create streams that spins turbines, wood burned to heat house

hydroelectric

running water- dams, water runs through turbines to generate electricity

renewable

something that gives us energy and will not run out. Continuously regenerating itself

resource

a source of supply, especially one that can be readily drawn upon when needed

nonrenewable

something that gives us energy and will run out, once consumed, it will not regenerate itself within our lifetime

pros of nonrenewable

reliable source of energy can be transported/ moved, creates jobs

cons of nonrenewable

bad for enviroment, creates large scars, creates pollutions, kills ecosystems, will eventually run out, dangerous

pros of renewable

will not run out, eco friendly, cheaper in long run, creates jobs

cons of renewable

expensive upfront cost, usually take up a lot of room, not reliable, depends on weather

Pistons

a disk or short cylinder fitting closely within a tube in which it moves up and down against a liquid or gas, used in an internal combustion engine to derive motion, or in a pump to impart motion.

nuclear fussion

fusing atoms together which releases energy

nuclear fission

a nuclear reaction in which a heavy nucleus splits spontaneously or on impact with another particle, with the release of energy.
