Angular momentum (sometimes called moment of momentum or rotational momentum) is the rotational analog of linear momentum. It is an important physical quantity because it is a conserved quantity – the total angular momentum of a closed system remains constant.
Describe the vector nature of angular momentum. Find the total angular momentum and torque about a designated origin of a system of particles. Calculate the angular momentum of a rigid body rotating about a fixed axis. Calculate the torque on a rigid body rotating about a fixed axis.

We will first introduce the concept of angular momentum for a point-like particle of mass m with linear momentum p about a point. S , defined by the equation . L.
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 kgm2 s−1.
16 kwi 2021 · The angular momentum of a mass M relative to a point O is \[\mathbf{L}=\mathbf{r} \times \mathbf{p}\label{11.6}\] where p is the ordinary kinetic momentum of the mass. The angular momentum is zero if the motion of the object is directly towards or away from the origin, or if it is located at the origin.
