Document Summary
Process of hearing: undisturbed air is in equilibrium air that is not being acted on, when external force acts on air particles, it results in. Rarefaction- particles moving further apart: air is a fluid (different from a liquid) and has mass. Fluid is the ability to move in a fluid motion. Liquid is an actual physical state of something. Because air has mass it has inertial properties. Likelihood that something put into motion is going to stay in motion unless something acts on it. This is what creates (cid:498)waves(cid:499) of sound; flow of energy, not flow of particles: vibratory motion. Path caused by an object moving back and forth (air particles are what is moving back and forth) Displacement- distance of a vibrating body from equilibrium to the body at that instant (aka removing something from its place) Restoring force- force directed back to position at rest to (cid:498)restore(cid:499) body post-displacement.
