Simple Pendulum
A pendulum swings back and forth with a regular beat. The time for one full swing is its time period.
- Time period T
- 2.01 s
- Time
- 0 s
- Full swings
- 0
Gravity
Try this
- Double the length. Does the time period double?
- Change the swing angle. Does the period change much?
- How would a pendulum clock run on the Moon?
Key ideas
- T = 2π√(L/g) for small swings.
- A longer pendulum swings more slowly.
- The mass of the bob does not change the time period.
