Answer

Activity:

Suspend a metallic ball (bob) by a long thread from a rigid support. Your simple pendulum is ready.

Set the simple pendulum in motion.
Note the time in your watch when bob is at an extreme position (say A).
When the bob again comes to the position A, count 1 (one). Each time the bob reaches this position (A), increase the count by 1 (one).

Check the time after 25 such oscillations. Find the time taken in 25 oscillations.
