Question

5. Periodic motion and oscillatory motion​

Answer 1

Answer:

Periodic motion is defined as the motion that repeats itself after fixed intervals of time. ... 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

Answer:

Periodic motion. A motion that repeats itself after equal intervals of time is called periodic motion.

Oscillatory motion can be termed as the repeated motion in which an object repeats the same movement over and over. ... In the absence of friction, the oscillatory motion would continue forever; but in the real world, the system eventually settles into equilibrium
