Momentum diffusion — refers to the diffusion, or spread of momentum between particles (atoms or molecules) of matter, usually in the liquid state. In the case of the laminar flow of a liquid past a solid surface, momentum diffuses across the boundary layer which… … Wikipedia
Zero-point energy — is the lowest possible energy that a quantum mechanical physical system may have; it is the energy of its ground state. All quantum mechanical systems undergo fluctuations even in their ground state and have an associated zero point energy, a… … Wikipedia
Momentum exchange tether — Momentum Exchange Tethers is one of many applications for space tethers. This sub set represents an entire area of research using a spinning conductive and/or non conductive tether to throw spacecraft up or down in orbit (like a sling), thereby… … Wikipedia
Zero Moment Point — is a concept related with dynamics and control of legged locomotion, e.g., for humanoid robots. It specifies the point with respect to which dynamic reaction force at the contact of the foot with the ground does not produce any moment, i.e. the… … Wikipedia
Momentum — This article is about momentum in physics. For other uses, see Momentum (disambiguation). Classical mechanics Newton s Second Law … Wikipedia
Momentum (technical analysis) — For other uses of Momentum , see Momentum (disambiguation). Momentum and rate of change (ROC) are simple technical analysis indicators showing the difference between today s closing price and the close N days ago. Momentum is the absolute… … Wikipedia
momentum, conservation of — ▪ physics 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 constant. Momentum is equal to… … Universalium
Zero-point field — In quantum field theory, the zero point field is the lowest energy state of a field, i.e. its ground state, which is non zero. [cite book | last = Gribbin | first = John | title = Q is for Quantum An Encyclopedia of Particle Physics | publisher … Wikipedia
Zero-phonon line and phonon sideband — The zero phonon line and the phonon sideband jointly constitute the line shape of individual light absorbing and emitting molecules (chromophores) embedded into a transparent solid matrix. When the host matrix contains many chromophores, each… … Wikipedia
Momentum operator — See also: Momentum In quantum mechanics, momentum is defined as an operator on the wave function. The Heisenberg uncertainty principle defines limits on how accurately the momentum and position of a single observable system can be known at once.… … Wikipedia
Momentum thickness — In aeronautics and viscous fluid theory, the boundary layer thickness ({delta}) is the distance from a fixed boundary wall where zero flow is considered to occur, and beyond {delta} the fluid is considered to move at a constant velocity. This… … Wikipedia
