Question

4. What measurable property/properties affects the period of a pendulum?
7.Give another example of periodic motion other than simple harmonic motion.
8. If you landed on the moon, could you use the pendulum method to find "g" there? Explain.

Answer 1

4. What variables affect the period of a pendulum? Well, possible variables are the mass of the bob, the length of which the string hangs, and the angular displacement.[Or called the arc angle is the angle that the string makes with the vertical when released from rest].
I will post the other answers too :)

Answer 2

7. Another examples could be a sound wave
8. Yes, because of the gravitational acceleration.
Hoped it helped! :)

Answer 3

thanks for your help I truly appreciate it

Answer 4

how is the slope of t^2 vs l graph related to acceleration due to gravity?
