Potential energyPotential energy U or E , a kind of scalar potential, is energy by virtue of matter being able to move to a lower-energy state, releasing energy in some form. For example a mass released above the Earth has energy resulting from the gravitational attracti Potential differenceIn the physical sciences, potential difference is the difference in potential between two points in a conservative vector field. In engineering, it is sometimes described as the across variable, where flux is the through variable. Production The product o Potential flowFluid dynamics In fluid dynamics, potential flow also know as irrotational flow (of incompressible fluids) is steady flow defined by the equations : (zero rotation no viscosity) : (zero divergence volume conservation) Equivalently, : where: v is the vecto PotentialIn physics, a potential is a scalar quantity that can be used to analyze the effects of complicated vectorial forces and similar quantities by means of simple conservation laws. The most common examples are forms of potential energy (and the related case Potential flow in two dimensionsIn fluid dynamics, potential flow in two dimensions is simple to analyse using complex numbers. The basic idea is to define a holomorphic or meromorphic function. If we write : then the Cauchy-Riemann equations show that : (it is conventional to regard al Potential gradientIn electrostatics, the potential gradient is the difference of electric potential, per unit distance (vertical unless otherwise specified) between two points.
