Question

A pendulum is set in motion. Consider what will happen to the frequency or period in each of the following situations.
Increase Stay the same Decrease  If the mass of the pendulum is cut in half, the period will _______.
Increase Stay the same Decrease  If the length of the pendulum is cut in half, the period will _______.
Increase Stay the same Decrease  If the amplitude of the motion is cut in half, the period will ______.
Increase Stay the same Decrease  If the length of the pendulum is cut in half, the frequency will _______.
Increase Stay the same Decrease  If the acceleration due to gravity is decreased (suppose you travel to the surface of the moon), the frequency will _______.

Explanation / Answer

f is independent of amplitude so period = 1/f STAYS THE SAME

If g decreases then f DECREASES

F is independent of mass so it STAYS THE SAME

If the length is cut in half the frequency INCREASES

If the length is doubled the frequency decreases so the period INCREASES
