Examples
Examples Simple pendulum A simple pendulum exhibits approximately simple harmonic motion under the conditions of no damping and small amplitude.
Mass on a spring A mass m attached to a spring of spring constant k exhibits simple harmonic motion in closed space.
Mechanical oscillators SHM, DHM, SHO, and DHO refer to simple harmonic motion, damped harmonic motion, simple harmonic oscillator and damped harmonic oscillator respectively.
Thus simple harmonic motion is a type of periodic motion.
While simple harmonic motion oscillates with only the restoring force acting on the system, damped harmonic motion experiences friction.
