Angular velocity: the velocity with which an object is moving around a fixed axis of rotation (this is different from ordinary velocity!); different points on a rotating rigid body move different distances in a given time interval, depending on how far the point lies from the axis; but, because the body is rigid, all points rotate through the same angle in the same time; at any instant, every part of a rotating body has the same angular velocity (rad/s); linear velocity = r x alpha

The frequency, period, and angular frequency of a mass on a spring.

Forced oscillation (driven oscillation): if apply a periodically varying driving force with angular frequency to a damped harmonic oscillator; the angular frequency with which the mass oscillates is equal to the driving angular frequency; if we force the oscillator to vibrate w/ angular freq nearly equal to angular frequency: it is naturally disposed to oscillate at a certain freq, so we expect the amplitude to be larger than when the 2 are very different; little damp: sharp A peak when…

PRODUCT DESCRIPTION This quantitative, inquiry based laboratory exercise for physics or physical science classes examines the angular frequency of a mass attached to a spring and set into simple harmonic motion. Hooke's Law, otherwise known as the spring force, is also examined.
