400
When would the kinetic energy of a car falling off a cliff be the greatest?
At the bottom, before it hits the ground
400
This type of energy is caused by vibrations
Sound energy.
400
State the Law of Conservation of Energy.
Energy can be not be created or destroyed, it is simply transformed from one form to another
500
A solar panel on the roof of a building used to heat and cool the building.
Radiant energy -> electrical energy
500
Stronger -- higher frequency than purple light.
Ultraviolet light
500
This form of energy can be EITHER potential or kinetic
Mechanical energy (Potential when stored, as in a stretched rubber band & kinetic when in motion, as in a runner or moving car)
500
The sun is an example of this form of energy. (GIVE ALL FORMS)
Heat, Radiant, and Nuclear

What is the difference between reflection & refraction?
Reflection is bouncing back of a wave (into the same medium) while refraction is bending of a wave when going from one medium to the other.
