| Abstract: | From the path of instant center of velocity in plane motion of rigid body, it has been proved that the instant centers of both velocity and acceleration are coincident at the initial instant starting to move. Under this condition, this is handier to operate than the method of the composition of acceleration to solve dynamical problems. |

| Keywords: | path of instant center of velocity initial instant of motion instant center of velocity instant center of acceleration coincidence. |
