WebThe defining equation of SHM. By Newton’s Second Law, SHM can be defined as the following equations. where x0 is the amplitude (maximum displacement), x is the displacement, v is the velocity, and a is the acceleration. The angular frequency ( w ) is related to the period of the SHM by the following equation.
