Periodic Motion

Periodic motion is a motion that repeats at certain time intervals, such as a rocking chair moving back and forth. Another example would be a swinging pendulum. The time it takes for the pendulum to complete one oscillation is called the period ‘T’, which is usually measured in seconds. The term ‘period’ is used to describe the time it takes for an event to happen, regardless of whether that event is repetitive or not.

    Frequently Asked Questions about Periodic Motion

    Are all periodic motions simple harmonic motions?

    No, periodic motions are not all simple harmonic motions. They can also be circular motions.

    How is time measured using periodic motion?

    We can measure time by using periodic motion if we know the period of the motion, which is the time it takes for the motion to complete one cycle. After that, we can count the periods and multiply the counted value with the value of the period to measure time in seconds.

    Are all periodic motions oscillatory?

    No, all periodic motions are not oscillatory, but all oscillatory motions are periodic motions because they repeat themselves at certain time intervals called periods.
