The length of the pendulum and the acceleration of gravity determine the period of a pendulum.
Explanation:
We all are familiar with the pendulum and its motion. The way it swings from its rest position to the left and right ends with specific amplitude.
A pendulum can be simply defined as an object hung of a static point with a bob connected to it through a string.
When the bob is raised to the either direction from its rest position, it swings back and forth because of the acceleration (g). A complete back and forth swing of a bob from its rest position in the pendulum is counted as one complete period of a pendulum.
This primarily depends on length and acceleration. For simple pendulums, formula to evaluate its period is,
[tex]T=2 \pi \sqrt{\frac{L}{g}}[/tex]
Where,
L- length of the string from the static suspension point to the bob in the pendulum
g- Acceleration due to gravity = 9.8 [tex]m / s^{2}[/tex]
