The period of a simple pendulum does not depend on the mass of the pendulum bob. The period of a simple pendulum depends only on its length. The period of a simple pendulum is given by the following equation. Solve for g. Show work. From the pivot to the middle of the ball.
P is the pivot point.
L is the length of the pendulum. M is the mass. The angleTheta is the amplitude. The maximum displacement from the equilibrium position. It depends on the length and the acceleration of gravity.
