A pendulum is a freely hanging weight suspended from a pivot. The following laws are derived from the time of oscillations of a pendulum.
The law of length: The period of a pendulum is directly proportional to the square root of the length of the pendulum, that means T α √l
The law of acceleration: The period of a pendulum is inversely proportional to the square root of the acceleration due to gravity, that means T α 1 /√g
The law of mass: The time period of a pendulum is independent of the hanging weight.
The law of amplitude: The period and amplitude of a pendulum are independent, given the amplitude is small.
