The motion analysis derived for use within a translating reference frame is not capable of including motion for the point occurring with in the translating frame.
2. when a car rolls on pavement that instantaneous center of one of its wheels is located on the wheel axle.
3. the motion of a rigid body is a translation, the moment of the external forces about any axis is zero
4. a translation of a rigid body is equivalent to a rotation about an infinitely distant axis.
5. the angular velocity of a rigid body that undergoes plane motion depends on the reference line from which it’s angle of rotation is measured.
