Introduction to oscillation

Oscillation:-

• Oscillatory motion :-

   It is a 'to' and 'fro' periodic motion.

              e.g :- 1)Motion of a pendulum is a to and fro periodic motion. 

                   

           It is a to and fro periodic motion.

           2) If mass is attached to a spring and if I displace it from its constant position , it will perform oscillatory motion.

                   

              It is also a to and fro periodic motion.

•  All oscillatory motions are periodic in nature but All periodic motions are not oscillatory in nature🌿🍃. 

          e.g: -1) Motion of the earth 🌎 around the sun ☀ is periodic but not oscillatory but Motion of the simple pendulum is “to and fro” oscillatory but also repeated periodic motion.
