Simple Harmonic Motion FrequencyThe frequency of simple harmonic motion like a
mass on a spring is determined by the mass m and the stiffness of the spring
expressed in terms of a spring constant k ( see Hooke's
Law): 


Mass on Spring Resonance



Mass on Spring: Motion SequenceA mass on a spring will trace out a sinusoidal pattern as a function of time, as will any object vibrating in simple harmonic motion. One way to visualize this pattern is to walk in a straight line at constant speed while carriying the vibrating mass. Then the mass will trace out a sinusoidal path in space as well as time.

Energy in Mass on SpringThe simple harmonic motion of a mass on a spring is an example of an energy transformation between potential energy and kinetic energy. In the example below, it is assumed that 2 joules of work has been done to set the mass in motion.
