Posted 18 January 2012 - 10:33 PM. My kids love ABC mouse -but really its just a game for them - they don't learn much from it. They just do the lessons to earn more tickets to buy things at the store -because that is what they are really interested in.
A pendulum is a weight suspended from a pivot so that it can swing freely. When a pendulum is displaced sideways from its resting, equilibrium position, it is subject to a restoring force due to gravity that will accelerate it back toward the equilibrium position.he period of swing of a simple gravity pendulum depends on its length, the local strength of gravity, and to a small extent on the maximum angle that the pendulum swings away from vertical, Î¸0, called the amplitude.
Pendulum clock - Mechanism. 1  The mechanism which runs a mechanical clock is called the movement. 2  A power source; either a weight on a cord or chain that turns a pulley or sprocket, or a mainspring. 3  A gear train (wheel train) that steps up the speed of the power so that the pendulum can use it.
