# Virtual Lab - Simple Pendulum

A simple pendulum consists of a mass suspended by a (massless unâstretchable) string. When the** mass or bob** is pulled to one side and then released it oscillates about the equilibrium position. Provided the angle between the string and the vertical is small (ideally less than 10^{o}) then the pendulum undergoes simple harmonic motion with a period ** T** proportional to the square root of the length of the string and independent of the mass of the bob. This can be written as

where **T **is the period of the pendulum,

** L** is the length of the pendulum (to the centre of the mass)

** g** is the acceleration due to gravity
