A simple pendulum consists of a small metallic ball or a piece of stone suspended from a rigid stand by a thread. The metallic ball is called the ........... of the pendulum.

• Oscillation

• Extreme position

• Bob

• Thread

The time taken by the pendulum to complete one oscillation is called its .......... .

• Time period

• Time speed

• Distance covered

• Total time

The time taken by a simple pendulum to complete each oscillation remains ......... .

• Different

• Same

• Both (a) and (b)

• None of the above

From the images given below choose the image of a Simple pendulum.

The formula to find the total time taken by a simple pendulum is:

• Distance 'multiplied by' Speed

• Time period 'divided by' Number of oscillations

• Time period 'multiplied by' Number of oscillations

A simple pendulum takes 30s to complete 18 oscillations. What is the time period of the pendulum?

• 166.0 s

• 0.166 s

• 16.6 ss

• 1.66 s

The time period of a simple pendulum is 1.6 s. Find the total time taken by it in 28 oscillations.

• 448 s

• 44.8 s

• 4.48 s

• 0.448 s

The pendulum is said to have completed one (a)   when its Bob starting from the mean position, moves to the extreme positions and comes back to the mean position.
