| Abstract: | The article has deduced the argular moment of planar motion of rigid body with respect to any point in its plane of motion by method of motional resolution. Taking instantaneous centre of velocity of planar figure as moment eentre, the author has deduced the principle of moment of momentum of planar motion of rigid body relative to instantaneous centre of velocity. |
