Question

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

Choose: increase, same, decrease   

Explanation / Answer

As T=2pi*sqrt(l/g)

F=1/t

1)becomes sqrt(2) times(increase)

2)constant

3)constant

4)becomes 1/sqrt(2) times (decrease)

5)decrease
