Question

(1) Name the extreme position of the swing.
(i) Which is the mean position of the swing?
(iii) What kind of motion does the swing show?
(iv) Does it show non-periodic motion? Give
reason
(V) If the swing takes 5 s to complete
25 oscillations, then what is the time period
of the swing?​

Answer 1

Answer:

• Mean position is the position of the bob when the freely suspended pendulum is at rest.

• Extreme position is the position of the bob at the maximum distance from the mean position.

• Periodic Motion

• A periodic motion is a type of motion which is repeated in equal intervals of time. While dancing, a dancer performs various dance- steps and these movements do not have a fixed interval and may or may not repeat. as dance- movements have no probability of repetition, dancing is considered as a non- periodic motion.

1. Mean position is the position of the bob when the freely suspended pendulum is at rest. Extreme position is the position of the bob at the maximum distance from the mean position.
