Angular momentum is the property of any rotating object given by moment of inertia times angular velocity.
Angular momentum is an important quantity in physics because it is a conserved quantity that is the total angular momentum of a closed system remains constant.
SI units for angular momentum are kilogram meters squared per second.
Formula to calculate angular momentum.
Angular momentum is basically the product of the moment of inertia of an object and its angular velocity.
In physics, angular velocity refers to how fast an object rotates or revolves relative to another point.
The mass of a disc is 0.02 Kg and its radius is 0.005m. When a DVD in a specific machine starts playing, it has an angular velocity of 160.0 radians/s. Determine the disc’s angular momentum.
Thus, the disc’s angular momentum is 0.016 Kg m/s .
