Oscillation of a Simple Pendulum

A simple pendulum consists of a ball point mass m hanging from a massless string of length L and fixed at a pivot point P When displaced to an initial angle and released the pendulum will swing back and forth with periodic motion By applying Newton s secont law for rotational systems the equation of motion for the pendulum may be obtained $$ tau = I alpha qquad Rightarrow qquad
