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 10o) 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
