31Angular momentum coupling — Coupling in science Classical coupling Rotational–vibrational coupling Quantum coupling Quantum mechanical coupling Rovibrational coupling Vibronic coupling Rovibronic coupling Angular momentum coupling …
32Kinetic energy — The kinetic energy of an object is the extra energy which it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its current velocity . Having gained this energy during its acceleration …
33Conservation of energy — This article is about the law of conservation of GPE in physics. For sustainable energy resources, see Energy conservation. Prof. Walter Lewin demonstrates the conservation of mechanical energy, touching a wrecking ball with his jaw. (MIT Course… …
34Dimensionless momentum-depth relationship in open-channel flow — Contents 1 Momentum in Open Channel Flow 1.1 What is Momentum? 1.2 Momentum in a Rectangular Channel 1.3 Why is Momentum Important? …
35Stress-energy-momentum pseudotensor — In the theory of general relativity, a stress energy momentum pseudotensor, such as the Landau Lifshitz pseudotensor, is an extension of the non gravitational stress energy tensor which incorporates the energy momentum of gravity. It allows the… …
36Angular momentum — For a generally accessible and less technical introduction to the topic, see Introduction to angular momentum. Classical mechanics Newton s Second Law …
37Fermi energy — The Fermi energy is a concept in quantum mechanics usually referring to the energy of the highest occupied quantum state in a system of fermions at absolute zero temperature. This article requires a basic knowledge of quantum mechanics.Note that… …
38Four-momentum — In special relativity, four momentum is the generalization of the classical three dimensional momentum to four dimensional spacetime. Momentum is a vector in three dimensions; similarly four momentum is a four vector in spacetime. The… …
39Zero-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… …
40Kinetic momentum — When a charged particle is interacting with an electromagnetic field, the kinetic momentum is a nonstandard term for the mass times velocity. It is distinguished from the canonical momentum, because the canonical momentum includes a contribution… …
