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.
The pendulum bob is a block of wood into which the bullet is fired. The bullet is stopped within the block and its momentum transferred to the pendulum. This momentum is determined from the amplitude of the pendulum swing. See Ballistics. The spherical pendulum is a simple pendulum mounted on a pivot so that its motion is not confined to a plane.
