What is kinetic energy?
the energy an object has due to its motion
What is elastic potential energy?
the energy associated with objects that can be compressed or stretched
What is mechanical energy?
the from of energy associated with the motion, position, or shape of an object
How do you find mechanical energy?
add potential and kinetic energy together
What is the unit for energy?
Joules
What are some examples of mechanical energy?
a bowling ball acting on the pins,or a basketball acting on the net
What is electromagnetic energy?
a form of energy that travels through space in waves
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?
states that when one form of energy is transformed to another, no energy is lost in the process
What is the definition of energy?
the ability to do work or cause change
WHat is chemical energy?
the potential energy stored in chemical bonds
What is power?
the rate at which energy is transferred or the amount of energy transferred in a unit
WHat is thermal 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
What is nuclear fusion?
when two or more nuclei are added or out together
