The period of simple pendulum

Explanation

The period of a simple pendulum at a given place is given by
`T=2pisqrt((L)/(g))`
where L is the length of the simple pendulum and g is the acceleration due to gravity at that place. From the above expression, the laws of simple pendulum are as follows :
(1) Law of length : The period of a simple pendulum at a given place (g constant) is directly proportional to the aquare root of its length.
(2) Law of acceleration due to gravity : The period of a simple pendulum of a given length (L constant) is inversely proportional to the aquare root of the acceleration due to gravity.
(3) Law of mass : The period of a simple pendulum does not depend on the mass or material of the bob of the pendulum.
(4) Law of isochronous oscillations or law of isochronism : The period of a simple pendulum does not depend on the amplitude of oscillations, if the amplitude is small.
