The angular momentum →l of a particle is defined as the cross-product of →r and →p, and is perpendicular to the plane containing →r and →p: →l = →r × →p. 11.5 Figure 11.9 In three-dimensional space, the position vector →r locates a particle in the xy-plane with linear momentum →p.

Answer: 21%. Explanation: Let the initial mass of the body be m and its velocity be v. Initial momentum of the body = mv . Initial KE = mv^2/2 . If the momentum increases by 10%, new momentum = mv + 10% of mv

Law of conservation of angular momentum: When no external torque is acting on a body then the angular momentum of that rotating body is constant. I 1 ω 1 = I 2 ω 2 (when τ = 0) Here I is the moment of inertia and ω is angular. velocity. Example:

Law of Conservation of Angular Momentum. The angular momentum of a system of particles around a point in a fixed inertial reference frame is conserved if there is no net external torque around that point: d→L dt = 0. or. →L = →l1 + →l2 + ⋯ + →lN = constant. Note that the total angular momentum →L is conserved.
