How does your body maintain energy?
by converting chemical energy into thermal energy
How does electric energy change to thermal energy?
electric energy puts off thermal heat
WHat is nuclear energy?
energy stored in the nucleus
What is potential energy?
energy that results from the position or shape of an object
WHen work is done on an object what happens to the object?
it gains energy
What is gravitational energy?
potential energy related to an object's height
What is the law of conservation of energy?

What is nuclear fission?
when the nucleus in an atom splits into two or more smaller nuclei
How does velocity affect kinetic energy?
when the velocity of an object doubles its its kinetic energy quadruples
