Question
The period of a periodic motion is the ________ interval of time after which the motion is __________.
- Average, repeated
- Mean, not repeated
- Largest, repeated
- Smallest, repeated
Hint:
periodic motion, in physics, motion repeated in equal intervals of time. Periodic motion is performed, for example, by a rocking chair, a bouncing ball, a vibrating tuning fork, a swing in motion, the Earth in its orbit around the Sun, and a water wave
The correct answer is: Smallest, repeated
A motion that repeats itself after a fixed interval of time is called periodic motion and the fixed interval of time is called period.
Average, repeated is correct option
