The period of a pendulum can be found by timing how long it takes to make one complete back and forth swing.
Explanation:
The period of a pendulum is the time it takes for the pendulum to make one complete oscillation.
The formula to calculate the period of a simple pendulum, in the small angle approximation, is the following:
[tex]T=2\pi \sqrt{\frac{L}{g}}[/tex]
where:
L is the length of the pendulum
g is the acceleration of gravity
By looking at the equation, we can make the following observations:
1) The period of the pendulum does not depend on the mass of the bob attached.
2) The period of the pendulum is proportional to square root of the length of the pendulum: the longer it is, the longer the period
3) The period of the pendulum is inversely proportional to the square root of the acceleration of gravity: therefore, on a planet with less gravity (for example, on the Moon), the period of the pendulum will be longer.
