Inertial Frame of Reference: If in a given system a free object does not experience any acceleration or force, the system is called the inertial frame. Any reference frame that moves with the constant velocity relative to an inertial frame of reference is itself an inertial frame. Newton's laws are found to be valid in these frames of references. Examples, a passenger in a car, moving with uniform velocity experiences no force on him.
