Angular momentum formula

Angular momentum is a vector quantity (more precisely, a pseudovector) that represents the product of a body's rotational inertia and rotational velocity (in radians/sec) about a particular axis. However, if the particle's trajectory lies in a single plane, it is sufficient to discard the vector nature of angular momentum, and treat it as a scalar (more precisely, a pseudoscalar) The angular momentum formula is the rotational equivalent to the linear momentum. Both of the concepts deal with how quickly anything is moving. Moreover, it also deals with how difficult it is to change the speed

The unit for Angular momentum is given as kilogram meter square per second (kg m2/s). Angular Momentum formula is made use of in computing the angular momentum of the particle and also to find the parameters associated to it Angular momentum is conserved because there are no external torques the satellite must deal with (gravity always acts parallel to the orbital radius). Because angular momentum is conserved, you can say that. Because the satellite is so small compared to the radius of its orbit at any location, you can consider the satellite a point mass. Therefore, the moment of inertia, I, equals mr 2. The. The total angular momentum of a body is the sum of spin and orbital angular momentum. In another way, angular momentum is a vector quantity that requires both the magnitude and the direction. For an orbiting object, the magnitude of the angular momentum is equal to its linear momentum Angular Momentum Formula Angular momentum relates to how much an object is rotating. An object has a constant angular momentum when it is neither speeding up nor slowing down. It is equal to the cross product of a length and a linear momentum Angular Momentum = Angular Velocity × Moment of Inertia Or, M = [M 0 L 0 T -1] × [M 1 L 2 T 0] -1 = M 1 L 2 T -1. Therefore, the angular momentum is dimensionally represented as M1 L2 T -1. ⇒ Check Other Dimensional Formulas

Relation between torque and angular momentum The angular momentum of a rotating rigid body is, L = I ω Differentiating the above equation with respect to time, dL/dt = I(dω/dt) = Iα where α = dω /dt angular acceleration of the body. But torque τ = Iα Therefore, torque τ = dL/dt Thus the rate of change of angular momentum of a body is. Based on this formula and the principle of angular momentum conservation, we can predict that in the absence of net external torque, if r is reduced ω would increase, and if r is increased ω would decrease.
