Hearing Science Module: Oscillations & Vibrations (U of Colorado)

Question 1

oscillations and vibrations that can be described and understood by the study of vibrating objects such as a pendulum, mass-spring system and tuning fork

Answer 1

Simple harmonic motion

Question 2

The source of sound is the back-and-forth motion of a mechanical object around its _ position. This back-and-forth motion is called an _ or _

Answer 2

Equilibrium. Oscillation, vibration

Question 3

And oscillation is due to the force of
