What is sliding friction?
600
A measure of the power contained in a sound wave and is indicated by the wave's amplitude.

what is a scalar?
800
A force that accelerates an object toward the center of a circular motion.
What is a centripetal force?
800
How high or low an audible tone sounds to the human ear, and describes how we perceive a sound's frequencies.
