Question

Define periodic motion.explain how rotation and revolution of the earth are exaamples of periodic motion​

Answer 1

Answer:

Periodic motion, in physics, motion repeated in equal intervals of time. Periodic motion is performed, for example, by a rocking chair, a bouncing ball, a vibrating tuning fork, a swing in motion, the Earth in its orbit around the Sun, and a water wave. Revolution of Earth: We all know that the Earth takes 365 days and 6 hours to complete one revolution around the Sun. This is a periodic motion. Rotation of Earth around its axis: Our planet Earth takes 24 h to complete one rotation around its axis. This is a periodic motion and it repeats again and again.

Answer 2

Periodic motion is performed, for example, by a rocking chair, a bouncing ball, a vibrating tuning fork, a swing in motion, the Earth in its orbit around the Sun, and a water wave. ... Thus, the period of the Earth's orbit is one year, and its frequency is one orbit per year.
