Class 11 Physics Oscillations Periodic and Oscillatory motions

Periodic and Oscillatory motions

Oscillations are defined as to and fro motion which repeat itself after regular intervals of time.In oscillations, the frequency of vibrations iscomparatively less. 

For example: The to and fro motion of a pendulum clock

 

Vibrations are defined as movement of object about its mean position and this motion can be linear, circular, periodic or non-periodic. If vibrations frequency is more and external force also acts on a body.

For eg: - Vibration of guitar string.When we move our fingers on the strings of guitar the strings vibrate so rapidly we can’t make it out when it comes to its mean position and when it goes to extreme position because the frequency is very high as a result it has vibratory motion.
