Pendulum Wikipedia

Simple gravity pendulum. The simple gravity pendulum is an idealized mathematical model of a pendulum. This is a weight (or bob) on the end of a massless cord suspended from a pivot, without friction.When given an initial push, it will swing back and forth at a constant amplitude.Real pendulums are subject to friction and air drag, so the amplitude of their swings
