WebAngular momentum is rotational momentum that is conserved in the same way that linear momentum is conserved. For a rigid body, the angular momentum (L) is the product of the moment of inertia and the angular velocity: L = I ω. For a point of mass, angular momentum can be expressed as the product of linear momentum and the radius ( r ): L = mvr. WebThe magnitude of its tangential velocity is vi = Riω. Because the vectors →viand→ri are perpendicular to each other, the magnitude of the angular momentum of this mass segment is. li = ri(Δmvi)sin90°. Figure 11.12 (a) A rigid body is constrained to rotate around the z-axis. The rigid body is symmetrical about the z-axis.
