With the help of an activity explain how will you measure the time period of a simple pendulum

Set the simple pendulum in motion. Note the time in your watch when bob is at an extreme position (say A). ... Each time the bob reaches this position (A), increase the count by 1 (one). Check the time after 25 such oscillations.

Answer 2

Answer:

activity

Explanation:

• suspend suspend a metallic ball (Bob) bi a long trade 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)
