Question

3. Define the following
a. Periodic motion
b. Circular motion​

Answer 1

Circular Motion: Motion of object in a circular path is called circular motion. ... Periodic Motion :Motion of a object which repeats itself after a certain period of time is called periodic motion. For example : Motion of Earth around the sun isperiodic as well as circular as it repeats it motionafter time of 365 days.

Answer 2

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.

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
