What is One Oscillation of a Pendulum?

Answer: When a pendulum begins at one extreme position A, goes to the other extreme position B, and then returns to the starting position A, this constitutes one complete oscillation for the pendulum. The length of time required to complete one cycle is referred to as the period. The period of the oscillation is maintained at the same value.

A primary pendulum consists of a heavy point mass called the “bob,” dangling from a stationary support using a massless and non-extendable thread. The pendulum’s motion starts when the bob is pulled away from its centre position to one side and then released. This sets the pendulum in motion, and the bob moves to either side of its central position in a zigzag pattern.
