[SHM= SIMPLE HARMONIC MOTION] The phase difference between forced oscillation of mass and driver oscillation is 180°. Driver oscillation refers to the oscillation of force causing the SHM. WebbHarmonic motion refers to the motion an oscillating mass experiences when the restoring force is proportional to the displacement, but in opposite directions. Harmonic motion is periodic and can be represented by a sine wave with constant frequency and amplitude. An example of this is a weight bouncing on a spring. Created by Sal Khan.
