• Angular momentum - Wikipedia

    en.wikipedia.org/wiki/Angular_momentum 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).

    www.britannica.com/science/angular-momentum 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. Angular momentum is a vector quantity, requiring the specification of both a magnitude and a direction for its complete description.

    www.merriam-webster.com/dictionary/angular%20momentum Angular momentum definition is - a vector quantity that is a measure of the rotational momentum of a rotating body or system, that is equal in classical physics to the product of the angular velocity of the body or system and its moment of inertia with respect to the rotation axis, and that is directed along the rotation axis.
  • Angular Momentum - an overview | ScienceDirect Topics

    www.sciencedirect.com/topics/engineering/angular-momentum Angular momentum (AM) is one of the fundamental conserved quantities in physics, along with energy and linear momentum. Whereas energy conservation arises from invariance for time translation, and momentum conservation reflects the homogeneity of space, it is the isotropy of space that gives rise to conservation of AM. ...

  • Angular Momentum – The Physics Hypertextbook

    physics.info/rotational-momentum The Earth's angular momentum is decreasing, so the Moon's must increase. The only way it can do this is by moving into a higher orbit around the Earth. Thus, the distance to the farthest point of the lunar orbit is increasing by about 3.8 centimeters per year."

    www.sparknotes.com/physics/rotationalmotion/angularmomentum/section2 Initially, the wheel has an angular momentum in the upward direction. When the person turns over the wheel, the angular momentum of the wheel reverses direction. Because the person-wheel-chair system is an isolated system, total angular momentum must be conserved, and the person begins to rotate in an opposite direction as the wheel. The vector ...

Actually let me be a little bit more careful here.

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. Angular momentum is a vector quantity.It is derivable from the expression for the ...
