When work is done on or by a system the total energy of the system is changed.Energy is needed to do the work.

Electromagnetic-energy from a electromagnetic field

Potential energy is stored energy because of its position or state

Kinetic energy is energy of movement.

In any transfer of energy among objects in a closed system (one where no external forces act and no external work can be done on or by the system), the total energies (potential and kinetic) of the system remains constant.

The sun because everything needs sun light or heat and that is what the sun does to the earth. It allows plants and animals to function. It also heats the earth so we can use geothermal and use the sun for solar energy.

These are non renewable resources Fossil fuels-coals, natural gas, oil Nuclear-uranium

These are renewable resources Solar-energy from the sun Hydro-energy from moving water Geothermal- energy from hot rocks under

the earth’s surface Wind-energy from rise and fall of tides Waves-energy from ocean waves Biomass-energy from burning plant

material Incinerators-energy from burning trash

Traditional energy is cost more and can eventually run out.

Alternative energy won’t ever run out because you use the wind, sun earths core or waves. Those will always happen and it is cost friendly.

Walk to school instead of ride the bus Don’t run the water the whole time I brush

my teeth. Shorter showers Shut the lights off when you leave the

room Don’t leave the TV on all night Ride my bike to work instead of drive my

car Shut the computer off when done with it

and not leave it running Don’t waste food

Uranium

Page 12: By Student S. Is the ability to do work  When work is done on or by a system the total energy of the system is changed. Energy is needed to do the work

It is made into steam then it is transferred into a gas which then powers a pump

Nuclear energy is the use of sustained nuclear fission to generate heat and electricity. A nuclear fission is radioactive decay process in which the nucleus of an atom splits into smaller parts. Nuclear fusion is the process by which two or more atomic nuclei join together, or "fuse", to form a single heavier nucleus

Because It is radioactive and the radiation can cause cancer

The fossil fuels make it so we put a lot of CO2 into the air and pollute the air. The renewable resources allow us to make energy and it will be clean energy.
