Question

The motion described by the needle of the sewing machine is oscillatory motion.

• A. True
• B. False

Answer 1

The correct option is A True

Explanation:

1. Oscillatory motion can be differentiated from other types of motion based on the fact that the body which is executing this type of motion always moves in to and fro format about a given mean point.
2. The same to and fro type of motion is repeated by a body regularly at equal intervals of time. This type of motion can be observed in a simple pendulum oscillation.
3. The needle of a sewing is always oscillatory in motion because the needle always follow the same rule i.e., it moves up and down in regular intervals of time..

Hence, the given statement is True.
