Also called linear momentum.Mechanics. a quantity expressing the motion of a body or system, equal to the product of the mass of a body and its velocity, and for a system equal to the vector sum of the products of mass and velocity of each particle in the system.
momentum product of the mass of a particle and its velocity. Momentum is a vector quantity; i.e., it has both magnitude and direction. Isaac Newton's second law of motion states that the time rate of change ...
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. The Earth has orbital angular momentum by ...
momentum, conservation of general law of physics according to which the quantity called momentum that characterizes motion never changes in an isolated collection of objects; that is, the total momentum of a system remains ...
Charter Schools Gain Momentum By 2003 more than 684,000 U.S. students attended charter schools-publicly funded schools that pledged better academic results and were unencumbered by many of the regulations governing ordinary ...
population An important and often misunderstood characteristic of human populations is the tendency of a highly fertile population that has been increasing rapidly in size to continue to do so for decades after ...
physical science, principles of The total angular momentum (also called moment of momentum) of an isolated system about a fixed point is conserved as well. The angular momentum of a particle of mass m moving with velocity v at the ...
spectroscopy There are a set of angular momentum quantum numbers associated with the energy states of the atom. In terms of classical physics, angular momentum is a property of a body that is in orbit or is ...
mechanics A particle of mass m and velocity v has linear momentum p = mv. The particle may also have angular momentum L with respect to a given point in space. If r is the vector from the point to the ...
mechanics Newton's second law, in its most general form, says that the rate of a change of a particle's momentum p is given by the force acting on the particle; i.e., F = dp/dt. If there is no force acting on ...
spectroscopy For atoms in the first three rows and those in the first two columns of the periodic table, the atom can be described in terms of quantum numbers giving the total orbital angular momentum and total ...
