Description
An object attached to a coil spring can exhibit oscillatory motion. Many kinds of oscillatory
motion are sinusoidal in time, or nearly so, and are referred to as simple harmonic motion. Real
systems generally have at least some friction, causing the motion to be damped. The automobile spring shown here has a
shock absorber (yellow) that purposefully dampens the oscillation to make for a smooth ride. When an external sinusoidal force is exerted on a system able to oscillate, resonance occurs if the driving force is at or near the natural frequency of oscillation.
