###### Answer: The mechanical energy transforms to thermal energy as the pendulum slows and eventually stops moving.

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 declines.

A pendulum clock is a clock that uses a pendulum a swinging weight as its timekeeping element. The advantage of a pendulum for timekeeping is that it is a harmonic oscillator: It swings back and forth in a precise time interval dependent on its length and resists swinging at other rates.From its invention in 1656 by Christiaan Huygens inspired by Galileo Galilei until the 1930s the …

There two types of motions that need to be addressed. One the motion of the swing of …
