Question

(a) Draw a neat, labelled diagram of an oscillating pendulum and label the following: mean position, extreme position, amplitude.
(b) Explain one oscillation with the help of the diagram.
(c) Define the following terms: one oscillation, time period of an oscillation, amplitude

Answer 1

(a)



(b)





One oscillation is the distance travelled by the pendulum from mean position to one extreme position, coming back to mean position, going to the other extreme position and then again coming back to mean position.

(c)
​One oscillation is the distance travelled by the pendulum from mean position to one extreme position, coming back to mean position, going to the other extreme position and then again coming back to mean position.

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

Amplitude of a pendulum is the distance from mean position to any of the extreme positions.
