Heart shape 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.Pendulum clocks must be stationary to operate any motion or accelerations will affect the motion of the pendulum causing inaccuracies so other mechanisms must be used in portable timepieces. They are now kept mostly for their decorative and antique value.Discount up to 10%if you need more information visit us www.justpro.co
