Question

How do you measure the time period of a given pendulum ? Why do you note the time for more than one oscillation ?​

Answer 1

Answer:

you can use following formulae to calculate time period of pendulum

T=

$2\pi \sqrt{l \div g}$

g= acceleration due to gravity,l=length of pendulum

Answer 2

Answer: To find the time period, the time for the time for the number of oscillations more than 1 is noted because the least count of stopwatch is actually either 1 s or 0.5 s. It cannot record the time period in fractions such as 1.2 s or 1.3 s or 1.4 s and so on.
