3Linear motion is when an object moves forward in a straight line. But there are times when the motion has constraints, such that it moves back and forth in regular motion. This is called periodic motion and can be seen in such examples of a weight on a string and seen how it swinging back and forth or a ball will bouncing up and down.
Examples of periodic motion
Periodic motion is any motion that repeats itself. Examples of periodic motion include a bouncing ball, vibrating spring, circular motion, and a pendulum.
Bouncing ball
If you drop a ball, it will start to bounce in a regular fashion. A good rubber ball or a super-ball will keep bouncing for a long time. Because of internal friction and air resistance, the ball bounces less and less each time, until it finally stops. A perfect ball-without friction-would bounce forever.
Vibrating spring
If you start a spring vibrating, it will continue to move back-and-forth for a long time. Internal friction slows it down or dampens its vibrations.
Circular motion
Spin a weight on a string around in circles. This is a periodic motion that repeats itself every rotation. The Earth rotates around the Sun in a periodic circular motion.
Pendulum
If you swing a weight on a string, it will go back and forth in regular periodic motion. Once it got started, such a pendulum would move back-and-forth forever if it was not for internal friction in the string and air resistance.
