Question

what is the similarity between oscillatory and periodic motion​

Answer 1

Answer:

The main difference is that oscillatory motion is always periodic but a periodic motion may or may not be oscillatory motion. For example, the motion of a pendulum is both oscillatory motion and periodic motion but the motion of the wheels of a car is only periodic because the wheels rotate in a circular motion.

Answer 2

HEY MATE,

ANSWER:}

Any motion that repeats itself at regular interval of time is called periodic motion.

 

Examples: Motion of the pendulum of a clock, motion of planets around the Sun, etc.

A to and fro or back and forth motion of a body along the same path, without any change in shape of the body, is called an oscillatory motion. Examples: Motion of a swing or pendulum, motion of the needle of a sewing machine moving up and down, etc.

All oscillatory motions are periodic but NOT all periodic motions are oscillatory. For example, motion of a planet around the Sun is periodic but not oscillatory
