Document Summary
Psychophysics: the scientific study of the relation between physical events and sensations. Psychoacoustics: the area of psychophysics that focus on the perception of sound. Difference between what you hear and what you say you hear. Scalar: quantity fully described by a magnitude (or numerical value) alone. Vector: described by both a magnitude and direction (velocity [time rate change in displacement], acceleration [time rate change in velocity]) Inertia= object at rest/motion tend to stay in rest/motion: net force= acting on an object in motion equals the product of mass and acceleration (force in motion = acceleration x mass). Additional force must be applied to a body in order to bring about a change in momentum. Greater force required to accelerate a greater mass: equal and opposite = forces of two bodies on each other are equal and opposite. Opposition to force: inertia (mass), momentum (stiffness?) and friction (resistance) Simple spring mass system-produces oscillation of a mass in space (pendulum.
