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 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 period will _______.
(Increase Stay the same Decrease) If the acceleration due to gravity is increased (suppose you travel to the surface of Jupiter), the frequency will _______.
(Increase Stay the same Decrease) If the mass of the pendulum is doubled, the frequency will _______.
(Increase Stay the same Decrease) If the length of the pendulum is doubled, the frequency will _______.

Explanation / Answer

1)the amplitude of oscillation is independent of its time priod or frequency.

2)time period becomes 1/ sqrt (2) times of its initial

3)Time period would decrease.

4)it is independent of its mass

5)frequency becomes 1/ (sqrt (2)) if initial

the formula is T = 2 *phi * sqrt (l/g)
