the rate of doing work

How fast the wave moves-the product of wavelength and frequency

The maximum displacement from equilbrium or the maximum distance that the particles of a wave’s medium vibrate from their rest position

Friction that opposes motion once the motion has already started.the friction that acts on objects that are moving relative to one another.

The average person can hear sounds with frequencies between 20 Hz and 20,000 Hz (20 kHz)

a theory based on the idea that particles of matter are always in motion

the ability to do work

The coldest temperature, 0 Kelvin, that can be reached. It is the hypothetical temperature at which all molecular motion stops.
