Description of Reversible Pendulum Apparatus
The Reversible Pendulum Apparatus consists of a rigid metal bar with two pivot points, one near each end of the bar. Reversible Pendulum Apparatus can be suspended from either pivot and swung. The two pivots are adjustable on the rigid metal bar and this allows the periods of swing to be adjustable. In use, it is swung from one pivot, and the period timed, and then turned upside down and swung from the other pivot, and the period timed.
The movable pivot is adjusted until the two periods are equal. At this point the period is equal to the period of an ideal simple pendulum of length equal to the distance between the pivots. From the period and the measured distance between the pivots, the acceleration of gravity can be calculated with great precision.
