What is angular momentum of a body?

Question

And how is it equal to mvr?Pls coz I am not understanding it correctly

Answer 1

linear momentum of a moving body is the "thing" that keeps it moving, given by mass x velocity.

angular momentum is the same "thing" that keeps an object spinning about its axis.

Answer 2

In physics the angular momentum of an object with respect to a reference point is a measure for the extent to which, and the direction in which, the object rotates about the reference point. In lay terms, angular momentum can be thought as the "amount of rotation" of the body.

In particular, if the body rotates about an axis, then the angular momentum with respect to a point on the axis is related to the mass of the object, the angular velocity and the distance of the mass to the axis.

Without applying torque to the object, with respect to the reference point, the angular momentum is constant. The angular momentum is a measure for the amount of torque that has been applied over time to the object. The object has rotational inertia that resists changes in rotational motion, quantified by the moment of inertia.

Angular momentum is an important concept in both physics and engineering with numerous applications. For example, the kinetic energy stored in a massive rotating object such as a flywheel is proportional to the square of the angular momentum.

Conservation of angular momentum also explains many phenomena in sports and nature.

Answer 3

Angular momentum is defined to be m(v x r) where v and r are vectors, linear velocity and the radius vector respectively.
