Generalized forces — are defined via coordinate transformation of applied forces, mathbf{F} i, on a system of n particles, i. The concept finds use in Lagrangian mechanics, where it plays a conjugate role to generalized coordinates.A convenient equation from which to … Wikipedia
Generalized coordinates — By deriving equations of motion in terms of a general set of generalized coordinates, the results found will be valid for any coordinate system that is ultimately specified. cite book |last=Torby |first=Bruce |title=Advanced Dynamics for… … Wikipedia
Generalized Helmholtz theorem — The generalized Helmholtz theorem is the multi dimensional generalization of the Helmholtz theorem which is valid only in one dimension. The generalized Helmholtz theorem reads as follows.Let:mathbf{p}=(p 1,p 2,...,p s), :mathbf{q}=(q 1,q 2,...,q … Wikipedia
Generalized function — In mathematics, generalized functions are objects generalizing the notion of functions. There is more than one recognised theory. Generalized functions are especially useful in making discontinuous functions more like smooth functions, and (going … Wikipedia
Internal energy — In thermodynamics, the internal energy of a thermodynamic system, or a body with well defined boundaries, denoted by U , or sometimes E , is the total of the kinetic energy due to the motion of molecules (translational, rotational, vibrational)… … Wikipedia
Strain energy density function — A strain energy density function or stored energy density function is a scalar valued function that relates the strain energy density of a material to the deformation gradient. : W = ar{W}(oldsymbol{F}) = hat{W}(oldsymbol{C}) =… … Wikipedia
Helmholtz free energy — In thermodynamics, the Helmholtz free energy is a thermodynamic potential which measures the “useful” work obtainable from a closed thermodynamic system at a constant temperature and volume. For such a system, the negative of the difference in… … Wikipedia

Principle of minimum energy — The principle of minimum energy is essentially a restatement of the second law of thermodynamics. It states that for a closed system, with constant external parameters and entropy, the internal energy will decrease and approach a minimum value at … Wikipedia
Interaction energy — In physics, interaction energy is the contribution to the total energy that is caused by an interaction between the objects being considered.The interaction energy usually depends on the relative position of the objects. For example, Q 1 Q 2 / (4 … Wikipedia
Hasegawa-Mima equation — The Hasegawa Mima equation, named after Akira Hasegawa and Kunioki Mima, is an equation that describes a certain regime of plasma, where the time scales are very fast, and the distance scale in the direction of the magnetic field is long. In… … Wikipedia
