This physics video tutorial explains the concept of simple harmonic motion. It focuses on the mass-spring system and shows you how to calculate variables such as amplitude, frequency, period, maximum velocity, maximum acceleration, restoring force, spring constant k, spring potential energy, kinetic energy, and mechanical energy in addition to describing the motion of the mass-spring system using a sinusoidal function such as sine or cosine. This video contains plenty of examples problems.
