3. Physical period: Uniform circular motion is a kind of periodic motion. The so-called periodicity refers to the fact that after a certain period of time, the moving object repeats back to its original position, and the instantaneous speed repeats back to its original size and direction. The time it takes for an object to move in a uniform circle is called a period.
