What are the principales of conservation of angular momentum |
|
Answer» According to the law of conservation of angular momentum if the total external torque on a system of particle is zero then the total angular momentum of the system is conserved i,e remains constant is equivalent to three scalar equationLx = k1 , Ly= k2, Lz= k3 hear k1 K2 and K3 are constant x y z are component of total angular momentum vector L along the x y z Axis respectively. Principle of conservation of angular momentum states that, If no external torque acts on a system, the total angular momentum of the system remains constant. If I be the moment of inertia of a body about a given axis of rotation and w be its angular velocity, then I w = constant. When objects collide without a net external torque, the angular momentum is constant. The two objects exert equal, but opposite angular impulses upon each other to maintain the total angular momentum of the colliding system. |
