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

OSCILLATORY MOTION :
   WHEN AN OBJECT MOVES BACK AND FRONT REPEATEDLY FOR SOME DURATION OF TIME  IT IS OSCILLATORY MOTION . EXAMPLE TUNING FORK  ,THE SPRING ETC .
 
PERIODIC MOTION :
  ANY MOTION WHICH REPEATS ITSELF IN A FIXED TIME INTERVAL IS CALLED PERIODIC MOTION . EXAMPLE-WAXING AND WANING OF MOON  ,SWING OF A CRADLE ETC
 
DISPLACEMENT:
   THE DISTANCE TRAVELLED BY THE VIBRATING  PARTICLE  AT ANY INSTANT OF TIME FROM ITS MEAN POSITION IS CALLED DISPLACEMENT.
