Explain that angular velocity is a vector and its direction is given by right hand screw rule. |
Answer» Solution :Angular velocity is a VECTOR, its direction is known by the right hand SCREW rule.  When the HEAD of a right HANDED screw rotates with the body, the screw advances in the direction will be the direction of angular velocity. The angular velocity of a body rotating about a fixed axis is parallel to the axis. It is shown in about figure. If a rigid body rotating in clockwise direction, then its angular velocity is negative and if rotating in anti-clockwise direction its angular velocity is positive. |
