Question

A simple pendulum takes 32 s to complete 20 oscillations. What is the time period of the

pendulum? (Hint – Time period = Time taken / No. of oscillations.)​

Answer 1

Answer:

Number of oscillations completed by the pendulum = 20

Time taken to complete 20 oscillations = 32 seconds

Time period of the pendulum is defined as the time taken by the pendulum to complete one oscillation.

Hence,

Time period =  

Time period = 1.6 seconds

Hence, the time period of the pendulum is 1.6 seconds

Explanation:

Answer 2

The time for one oscillation is called the period (T) it is measured in seconds. Acceleration – we can calculate the acceleration of the object at any point in it's oscillation using the equation below. In this equation; a = acceleration in ms-2, f = frequency in Hz, x = displacement from the central position in m.

Time period = Time taken / No. of oscillations

Time period = 32/20

Time period = 16/10

Time period = 8/5

Time period = 1.6 s
