1. Does the period of a simple pendulum depend on the mass?

2. Is the period constant over small angles? Does it vary when one reaches larger angles?

3. Does the period depend on the length of the pendulum?

4. If a single period takes exactly 1.00 second, how long does a period take on the moon? If the gravitational acceleration of the moon is 1/6 of that on the earth

## EXPERT ANSWER

1) No

2) The period of a pendulum is not dependent on the angle, and thus the height, from which it starts.

3) Yes, the period of a pendulum is determined 2π√(L/g), where L is the length of the pendulum.

4)

1s = 2π√(L/g)

By dividing g by 6, you basically are multiplying L by 6. Thus, by multiplying both sides by √6, you can get the period on the moon to be 1 * √6 or 2.45s.
