Angular momentum formula: Angular Momentum

Angular Momentum Angular momentum is the angular equivalent of linear momentum (p =mv) and is given by L =I ω, where I (kgm2) is the moment of inertia of an object about an axis and ω(rads−1) is its angular velocity about that axis. Angular momentum has the units kgm2s−1. A particle of mass m moving with velocity v and currently at a position r has an angular momentum of L =r ×p =mr ×v about the origin. In the same way that F = dtdp, for rotational motion τ = dtdL, where τ (Nm) is the resultant ... Angular momentum of an object with mass m, moving with velocity v along a circular path of radius r is given by the formula m " v " r. Definition of Angular Momentum Angular momentum is a measure of how difficult it is to change an object's rotational motion. It depends on the object's moment of inertia and its angular velocity. Angular momentum is a conserved quantity, meaning that the sum of the angular momenta of the particles in a closed system is always the same, even as that of individual particles can fluctuate. Angular momentum is, as noted, also a function of the distribution of mass about an axis. To gain an ...
