	Momentum - Wikipedia, the free encyclopedia
		Momentum is conserved in an electrodynamic system (it may change from momentum in the fields to mechanical momentum of moving parts).
		The amount of momentum that an object has depends on two variables: the mass and the velocity of the moving object in the frame of reference.
		For example the momentum of a 5-kg bowling ball would have to be described by the statement that it was moving westward at 2 m/s.

	Angular momentum - Wikipedia, the free encyclopedia
		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.
		Under this formalism, angular momentum is the 2-form Noether charge associated with rotational invariance (As a result, angular momentum isn't conserved for general curved spacetimes, unless it happens to be asymptotically rotationally invariant).
		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.

	Conservation of Momentum
		Momentum is defined to be the mass of an object multiplied by the velocity of the object.
		The conservation of momentum is a fundamental concept of physics along with the conservation of energy and the conservation of mass.
		Dealing with momentum is more difficult than dealing with mass and energy because momentum is a vector quantity having both a magnitude and a direction.

	The Physics Classroom
		In terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object.
		Momentum can be defined as "mass in motion." All objects have mass; so if an object is moving, then it has momentum - it has its mass in motion.
		Momentum is a physics term; it refers to the quantity of motion that an object has.

	momentum. The Columbia Encyclopedia, Sixth Edition. 2001-05
		Momentum is a vector quantity; i.e., it has both a magnitude and a direction, the direction being the same as that of the velocity vector.
		The angular momentum of a particle rotating about a point is equal to the product of the mass of the particle, its angular velocity, and the square of its distance from the axis of rotation.
		The momentum of a body should not be confused with its kinetic energy.

	Define momentum - a Whatis.com definition
		Momentum is a vector quantity that is the product of the mass and the velocity of an object or particle.
		Momentum, like velocity, can be expressed either as an average over a period of time or as an instantaneous value at a single moment in time.
		The direction of a momentum vector can be expressed in various ways, depending on the number of dimensions involved, and is the same as the direction of the velocity vector.

	Conservation of Angular Momentum
		As the adjacent figure illustrates the magnitude of the angular momentum in this case is L = mvr, where L is the angular momentum, m is the mass of the small object, v is the magnitude of its velocity, and r is the separation between the objects.
		Thus, conservation of angular momentum demands that a decrease in the separation r be accompanied by an increase in the velocity v, and vice versa.
		A crucial ingredient in the nebular hypothesis is the conservation of angular momentum.

	Momentum - Technical Analysis
		Momentum is a basic application of oscillator analysis, designedto measure the rate of price change, not the actual price level.

		If loss of momentum is experienced in a market at the same time as selling resistance is met or when buying power is temporarily exhausted, momentum and price peak simultaneously.

	Exploratorium: Science Snacks: Momentum Machine
		The conservation of angular momentum explains why an ice skater starts to spin faster when he suddenly draws his arms inward, or why a diver or gymnast who decreases her moment of inertia by going into the "tuck" position starts to flip or twist at a faster rate.
		A rotating object tends to remain rotating with a constant angular momentum unless it is acted upon by an outside twisting force.
		If the motion of a rotating system is not affected by an outside twisting force, then angular momentum is conserved for this system, which means that the angular momentum stays the same.
