Similarly, simple harmonic motion may be derived from the projection onto the axis of a circle of a point moving with constant speed on the circumference, as shown in the diagram below. See: Cycle, ...

Simple harmonic motion describes the vibration of atoms, the variability of giant stars, and countless other systems from musical instruments to swaying skyscrapers.

Simple harmonic motion is actually a lot like uniform circular motion, mathematically speaking. You can see this for yourself, if you compare the ball's motion on the spring to an object in ...

The angular velocity w of the motion is defined in radians per second as the angle q moved through per unit time, and is related to the FREQUENCY f by the equation: w = 2pf. The displacement d, whose ...
