Angular momentum is defined as: The property of any rotating object given by moment of inertia times angular velocity. It is the property of a rotating body given by the product of the moment of inertia and the angular velocity of the rotating object.
In physics, 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.
Sep 12, 2022 · 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.
May 13, 2024 · angular momentum, property characterizing the rotary inertia of an object or system of objects in motion about an axis that may or may not pass through the object or system.
The angular momentum of a rigid object is defined as the product of the moment of inertia and the angular velocity. It is analogous to linear momentum and is subject to the fundamental constraints of the conservation of angular momentum principle if there is no external torque on the object.
Defining angular momentum, \(\vec L\): \[\vec L\equiv I\vec\omega\label{L}\] We see that the direction of angular momentum is the same as the direction of angular velocity which can be obtained using the right-hand rule. The units of angular momentum are \(N\cdot m\cdot sec\), which is equivalent to \(kg\cdot m^2/ sec\).
