The motion which repeats at regular intervals of time is called repetitive motion. This is also called periodic motion. a) The motion of leaves and branches of a tree in breeze : In this case, leaves and branches move back and forth repeatedly.

Answer 2

We know that the pendulum of a clock repeats its motion after a particular time.

This kind of motion that repeats itself after a particular time is called periodic motion.

On the other hand, the motion of the leaf does not have any particular pattern.

It randomly moves according to the direction of the wind.

Therefore, the motion of the leaf is random.
