Answer 1

$\huge\underbrace\mathfrak\color{red}Answer$

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.

hope it helps

Have a good day ahead ☺☺❤❤

Answer 2

Answer:

periodic motion - a motion that repeats itself after equal intervals of time is known as periodic motion. Eg : a vibrating tunning fork

oscillatory motion - it is the to and fro motion of an object from its mean position. Eg : the motion of a swing.
