Question

Define periodic motion. Mention one difference between oscillatory and periodic motion.​

Answer 1

Answer:

Periodic Motion – This is a type of motion where the object repeats its motion after a fixed interval of time. Examples pendulum of a clock, motion of child on a swing etc.

Difference between Oscillatory Motion and Periodic Motion

Periodic motion is defined as the motion that repeats itself after fixed intervals of time. This fixed interval of time is known as time period of the periodic motion. Examples of periodic motion are motion of hands of the clock, motion of planets around the sun etc.

Oscillatory motion is defined as the to and fro motion of the body about its fixed position. Oscillatory motion is a type of periodic motion. Examples of oscillatory motion are vibrating strings, swinging of the swing etc.

Answer 2

Explanation:

Definition_

Periodic Motion :_ This is a type of motion where the object repeats its motion after a fixed interval of time

Difference b/w oscillatory and periodic motion as :_

The main difference is that oscillatory motion is always periodic but a periodic motion may or may not be oscillatory.

For example___

the motion of a pendulum is both oscillatory and periodic but the motion of the wheels of a car is only periodic because the wheels rotate in a circular motion.
