Question

Define Periodic Motion BRIEFLY​

Answer 1

Answer:

If an object repeats its motion along a certain path, about a certain point, in a fixed interval of time, the motion of such an object is known as periodic motion.

Answer 2

Answer:

Any motion of a system that is continuously and identically repeated. The time T that it takes to complete one cycle of an oscillation or wave motion is called the period, which is the reciprocal of the frequency. See pendulum; simple harmonic motion.
