The energy in a sound wave
A material that transfers heat well.
The measure of how much useful work a machine puts out compared to the amount of work put into it.
The ability to do work
The number of times a sound source vibrates in one second.
The force that works against motion between surfaces that touch.
A material that does not transfer heat very well.
the object being lifted or moved by a simple machine.
The highness or lowness of a sound.
The transfer of heat through space
When light strikes a surface and bounces off.
The bending of light as it passes from one material into another.
A range of light waves with different wavelengths and energies.
The distance an object moves in a certain amount of time.
When a force is used to move an object a certain distance.
This allows heat to move quickly from one object to itself. It is the opposite of an insulator.
