Question

what is difference between oscillatory motion and linear motion

Answer 1

The main difference is that oscillatory motion is always periodic but aperiodic motion may or may not beoscillatory motion. For example, themotion of a pendulum is bothoscillatory motion and periodic motionbut the motion of the wheels of a car is only periodic because the wheels rotate in a circular motion.

Answer 2

The main difference is that oscillatory motion is always periodic but a periodic motion may or may not be oscillatory motion. For example, the motion of a pendulum is both oscillatory motion and periodic motion but the motion of the wheels of a car is only periodic because the wheels rotate in a circular motion.
