Answer 1

The time of a simple pendulum can be calculated by the following formula = Total time taken/no of oscillations

Example : A simple pendulum takes 20s to complete 20 oscillations.What is the time period of pendulum

sol : No of oscillations = 20

Time taken = 20s

So,Time period = Time taken/no of oscillations = 20s/20 = 1 s

Hope this is helpful!

Answer 2

Answer:

• The period of a simple pendulum is T=2π√Lg T = 2 π L g , where L is the length of the string and g is the acceleration due to gravity.
• Calculate the period of oscillations according to the formula above: T = 2π√(L/g) = 2π * √(2/9.80665) = 2.837 s . Find the frequency as the reciprocal of the period: f = 1/T = 0.352 Hz . You can also let this simple pendulum calculator perform all calculations for you!
• Dividing the total time by the total number of oscillations, we get the time for one oscillation (or time-period) of the pendulum.
