Question

Define the following

a. periodic motion

b.circular motion​

Answer 1

Answer:

Circular Motion: Motion of object in a circular path is called circular motion. For example: Children playing ringa ringa roses or moving in a circle, motion of Earth around the Sun.

Periodic Motion : Motion of a object which repeats itself after a certain period of time is called periodic motion.

Answer 2

Answer:

a) 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.

b) In physics, circular motion is a movement of an object along the circumference of a circle or rotation along a circular path. It can be uniform, with constant angular rate of rotation and constant speed, or non-uniform with a changing rate of rotation.
