Question

Motion which repeats itself after regular intervals.
A. Oscillatory Motion
B. Vibratory Motion
C. Periodic Motion
D. None

Answer 1

Hint:Motion is the phenomena in which an item changes its location over time, as defined by physics. Displacement, distance, velocity, acceleration, speed, and time are all mathematical words used to describe motion. A frame of reference is attached to an observer, and the change in location of the body relative to that frame is measured as time passes.

Complete answer:
Periodic motion is defined as motion that repeats itself at regular periods of time. To and from motion is oscillatory motion. Periodic motion is defined as a motion that repeats itself at regular intervals of time. A tuning fork or the motion of a pendulum are examples of periodic motion; if you examine the motion, you'll notice that the pendulum only swings through the mean position after a specific amount of time.

The motion described above can alternatively be classified as oscillatory. An oscillatory motion occurs when the body travels back and forth around a fixed point. As a result, an oscillatory motion can be periodic but is not required. In physics, periodic motion is defined as motion that occurs at regular intervals. A rocking rocker, a bouncing ball, a vibrating tuning fork, a swing in motion, the Earth in its orbit around the Sun, and a water wave are all examples of periodic motion.

A period is the interval of time for a repeat, or cycle, of the motion in each occurrence, while the frequency is the number of periods per unit time. As a result, the Earth's orbit has a one-year period and a one-year frequency. A tuning fork with a frequency of 1,000 cycles per second and a period of 1 millisecond is an example of a tuning fork (1 thousandth of a second).

Hence option C is correct.

Note:Periodic motion is a subset of simple harmonic motion. The rocking chair, tuning fork, swing, and water wave all exhibit simple harmonic motion in the examples above, but the bouncing ball and the Earth in its orbit do not.
