The time period of a simple pendulum varies as follows —
- Length of pendulum (l) — Time period of a simple pendulum is directly proportional to the square root of the length of the pendulum. T ∝ √l
- Mass of bob — Time period of a simple pendulum is independent of the mass of the bob.
- Amplitude of oscillation — Time period of a simple pendulum is independent of the amplitude of oscillation
- Acceleration due to gravity (g) — Time period of a simple pendulum is inversely proportional to the the square root of acceleration due to gravity. T ∝ √(1/g)
