600 ÷ 50
Section C · long answer
- 6.
Describe how to find the time period of a simple pendulum.
Answer
Tie a bob to a thread about 100 cm long and hang it from a rigid stand. Pull it slightly to one side and release. Time 10 complete oscillations with a stopwatch and divide by 10. Repeat 3–4 times and take the average.
