Vector field — In mathematics a vector field is a construction in vector calculus which associates a vector to every point in a (locally) Euclidean space.Vector fields are often used in physics to model, for example, the speed and direction of a moving fluid… … Wikipedia
Velocity-addition formula — In physics, a velocity addition formula is an equation that relates the velocities of moving objects in different reference frames. Contents 1 Galilean addition of velocities 2 Special theory of relativity 3 Derivation … Wikipedia
velocity — /veuh los i tee/, n., pl. velocities. 1. rapidity of motion or operation; swiftness; speed: a high wind velocity. 2. Mech. the time rate of change of position of a body in a specified direction. 3. the rate of speed with which something happens;… … Universalium
Displacement (vector) — Displacement versus distance traveled along a path. A displacement is the shortest distance from the initial to the final position of a point P[1]. Thus, it is the length of an imaginary straight path, typically distinct from the path actually… … Wikipedia
Four-velocity — In physics, in particular in special relativity and general relativity, the four velocity of an object is a four vector (vector in four dimensional spacetime) that replaces classical velocity (a three dimensional vector). It is chosen in such a… … Wikipedia
Areal velocity — is the rate at which area is swept out by a particle as it moves along a curve. In many applications, the curve lies in a plane, but in others, it is a space curve.The adjoining figure shows a continuously differentiable curve in blue. At time t … Wikipedia
position vector — ▪ mechanics straight line having one end fixed to a body and the other end attached to a moving point and used to describe the position of the point relative to the body. As the point moves, the position vector will change in length or in… … Universalium
Conservative vector field — In vector calculus a conservative vector field is a vector field which is the gradient of a function, known in this context as a scalar potential. Conservative vector fields have the property that the line integral from one point to another is… … Wikipedia
Escape velocity — In physics, escape velocity is the speed where the kinetic energy of an object is equal to the magnitude of its gravitational potential energy, as calculated by the equation,:U g = frac{ Gm 1m 2}{r}.It is commonly described as the speed needed to … Wikipedia
