A simple pendulum consists of a bob of mass m suspended from a friction-less and fixed pivot with the help of a mass-less, rigid, inextensible rod of length L. Its position with respect to time t can be described by the angle theta (measured against a reference line, usually vertical line). As shown in the figure above the driving force is F=-mgsintheta where the -ve sign implies that the ...

The compound pendulum. A simple pendulum theoretically has the mass of the bob concentrated at one point, but this is impossible to achieve exactly in practice. Most pendulums are compound, with an oscillating mass spread out over a definite volume of space.Mass of the bob at the end of the pendulum-Changing the mass of the pendulum bob does not affect the frequency of the pendulum. Force of gravity -This accelerates the pendulum down. The momentum built up by the acceleration of gravity causes the mass to swing in the opposite direction to a height equal to the original position.)
