Energy 1
Energy is defined as the ability to do this
work
this is the sum of all forms of kinetic and potential energy
mechanical energy
uses uranium as a fuel source
nuclear energy
This is the kinetic energy of a 200.0 kg football player running at 5.0 m/s.
2500 J
kinetic energy could be described as the energy of this
motion
this kind of energy is renewed from the sea rising and falling
tidal energy
crop and animal waste
fossil fuel
This is the amount of gravitational potential energy of a 2.0 kg bird flying at 14 meters above the ground.
270 J
kinetic energy depends on these two things
mass and speed
these are the three main forms of fossil fuels
coal, oil, and natural gas
originates from hot water or rock beneath the earth's surface
geothermal energy
This is the height of a roof if a 40.0 kg man is standing on it with 4800 joules of potential energy.
12 m
"the total energy in a system remains constant over time" is an example of this law
conservation of energy
If energy is conserved, then a swing set should never stop on its own. This force causes the swing to stop by transforming some of the kinetic energy into thermal energy.
friction
is formed from the remnants of compressed plant and animal matter
Biomass energy
A plane moving at 4,000.0 m/s has 192,000,000,000.0 joules of energy. This is the plane's mass.
24,000. kg
Food is an example of this kind of potential energy
chemical
these are the three types of potential energy
gravitational, chemical, and elastic
uses the gravitational potential energy of water
hydroelectric energy
This is the quantity found if you take the square root of an object's kinetic energy divided by double its mass.
speed/velocity
