Pendulum
- The longer the pendulum, the wider the arc of the oscillation, the longer the distance travelled by the pendulum. The period of oscillation should thus, be longer as the time taken to cover the distance will increase.
- Formula to calculate period of oscillation:



Where:
T = period of oscillation
L = Length of pendulum in metres
G = acceleration of gravity (m/s)
|o| = amplitude (angle)

T² is proportional to L:


L 
T^{2 = constant}
