 Momentum - Wikipedia, the free encyclopedia
In general the momentum of an object can be conceptually thought of as the tendency for an object to continue to move in its direction of travel.
Conservation of momentum is a consequence of the homogeneity of space.
Momentum is conserved in an electrodynamic system (it may change from momentum in the fields to mechanical momentum of moving parts).

Angular momentum can also be calculated by multiplying the square of the displacement r, the mass of the particle and the angular velocity.
Constant angular momentum is extremely useful when dealing with the orbits of planets and satellites, and also when analyzing the Bohr model of the atom.
As angular momentum is constant in the absence of external torques, the angular velocity (rotational speed) of the skater has to increase.

Momentum is a physics term; it refers to the quantity of motion that an object has.
In terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object.
The direction of the momentum vector is the same as the direction of the velocity of the ball.

 Conservation of Momentum
The conservation of momentum is a fundamental concept of physics along with the conservation of energy and the conservation of mass.
Momentum is defined to be the mass of an object multiplied by the velocity of the object.
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.

Momentum can only be changed by changing the object's velocity or its mass.
Momentum depends on two thing, mass and velocity, but both have set masses, so it's up to you to change the velocities.
If the difference is positive, then the Rams player had more momentum, etc. Then I just divided the new momentum by the combined mass of the two players (since one is holding on to the other).

 The Physics Classroom
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.
It is not enough to say that the ball has 10 kg*m/s of momentum; the momentum of the ball is not fully described until information about its direction is given.
Objects at rest do not have momentum - they do not have any "mass in motion." Both variables - mass and velocity - are important in comparing the momentum of two objects.

 Define momentum - a definition from Whatis.com
Momentum is a vector quantity that is the product of the mass and the velocity of an object or particle.
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.
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.

 Conservation of Angular Momentum   (Site not responding. Last check: 2007-10-21)
A crucial ingredient in the nebular hypothesis is the 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.
