Dear Aakash

An inertial frame of reference (FOR) is a non-accelerating FOR , for example if a person is observing a moving car while at rest or while moving at constant velocity, he is in an inertial FOR. A non-inertial frame of reference is an accelerating FOR for example a rotating FOR. ( Rotation requires centripetal force and centripetal acceleration so any rotating object always requires a centripetal acceleration to rotate.)

                      Dear friend!  Inertial frame of reference is that which does not rotate or accelerate. Non inertial frame of reference is that which rotates or accelerates.

Inertial frame of reference is unaccelerated frame of reference in which Newton' laws of motion are valid.
Non-inetial frame of reference is accelerated in which Newton's laws of motion are not valid.
