Question

The time period of a simple pendulum is the time taken by it to travel from A to B and back to A or what else?

Answer 1

Answer:

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

When A and B are the two extremes, it can be said that time period is to travel from A to B and back to A .

Answer 2

Answer:

4(t1+t2) is the time taken by simple pendulum from A to B and back to A.

Explanation:

The total time taken by the bob to move from A to 0 is (t1+ t2) which is 1/4th time of one full cycle of the pendulum. A time period of pendulum i.e. time taken by pendulum to complete one oscillation from A to B and back to A will be 4(t1 + t2)
