The period of a pendulum is affected by the length of the pendulum, the mass of the bob, and the gravitational acceleration at the location where the pendulum is being used.
The period of a pendulum is directly proportional to the square root of its length. This means that as the length of the pendulum increases, its period will also increase.
The formula for calculating the period of a pendulum is T = 2π√(L/g), where T is the period, L is the length of the pendulum, and g is the gravitational acceleration.
The mass of the bob does not affect the period of a pendulum. The period only depends on the length of the pendulum and the gravitational acceleration.
A pendulum eventually stops swinging due to the effects of air resistance and friction. These forces cause the pendulum to lose energy and eventually come to a stop.
