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.
A pendulum bob is the round disk at the bottom of the pendulum and the diameter is the measurement from one side to the other. To select the proper bob size you would need to know the inside width of the clock case. You should have at least 2 inches on each side of the pendulum bob so it can swing in the case without hitting the sides.
