# Angular Momentum Definition And Formula

### Angular momentum is the quantity of rotation of a body which is the product of its moment of inertia and its angular velocity.

**Angular momentum definition and formula**.
The final angular momentum equals the change in angular momentum because the lazy susan starts from rest.
The total angular momentum of a system is the pseudovector sum of the angular momenta.
The angular momentum of a body about an axis is the product of its linear momentum and the perpendicular distance of the body from the axis in other words the angular momentum of a body is equal to cross product of its linear momentum and the.
When net torque is zero then both these are same.

Linear momentum p is defined as the product of mass and velocity. Spin is sometimes called angular momentum which is defined as. Just to brush up when an object of mass m moves with a speed v in a straight line we say that it has a linear momentum pmv. In our last post we have discussed on linear momentum.

Angular momentum is additive. To find the final velocity we must calculate from the definition of in. Definition formula examples angular momentum is sometimes a tough concept to grasp but with the right understanding and formula it can be a snap. Mass x velocity x radius where radius is the distance from the spinning object to the axisconservation of angular momentum one of the fundamental laws of physics observes that the angular rotation of a spinning object remains constant unless acted upon by external torque.

This is a quantity that is conserved when there are no external forces acting. The angular momentum equation. Physics also features angular momentum l. The more massive and faster moving an object the greater the magnitude of momentum.

When net torque is zero then both these are same. Iw2 represents final angular momentum and iw1 represents initial angular momentum. For continua or fields one uses integration.
