forms of energy
energy that is attached to outlets
electric
chemical -- electrical
battery
type of renewable resource using the waves of the ocean
tidal
a rubber band is stretched and let go that is potential energy transforming into
kinetic energy
most commonly used nonrenewable energy source
fossil fuels
moves from warmer to colder objects
thermal energy
solar light --- chemical --- kinetic
plant
energy source that cannot be used up
inexhaustible resource
the three types of potential energy
gravitational, elastic, chemical
where nuclear waste is stored
nuclear power plant
light waves, radio waves, and microwaves
radiant
kinetic --- mechanical --- electric
wind turbine
energy inside the earth
geothermal
two factors kinetic energy depends on
speed and mass
element nuclear energy comes from
uranium
sound energy cannot travel through
vacuum
chemical -- thermal -- sound -- kinetic
car
most widely used renewable energy source
hydroelectric
two cars are moving the same speed one car has a mass 150 g higher than the other. which car has a higher kinetic energy
the car that has the higher mass
formed on land from plants that died millions of years ago and were buried under rock
coal
total energy of an object or group of objects due to large-scale motions and interactions
mechanical energy
electrical -- thermal -- light -- mechanical -- sound
microwave
biofuel
object one is held at 120 m high and object two is held at 100 m high, which object has more potential energy
object 1
formed from ocean organisms that died and sank to the ocean floor. over millions of years they were buried under mud and sediment and changed
oil or petroleum
