Did you know ? A mathematical pendulum is a mathematical model of a pendulum. A mathematical pendulum is a mass point suspended on a thin perfectly solid fiber of negligible weight, while air resistance during the movement of the pendulum and friction in the suspension are neglected and the gravitational field is considered homogeneous. A mathematical pendulum is a mechanical oscillator that oscillates freely after initial energy is supplied.
