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
Tangent space — In mathematics, the tangent space of a manifold is a concept which facilitates the generalization of vectors from affine spaces to general manifolds, since in the latter case one cannot simply subtract two points to obtain a vector pointing from… … 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

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
Terminal velocity — A free falling object achieves its terminal velocity when the downward force of gravity ( Fg )equals the upward force of drag ( Fd ). This causes the net force on the object to be zero, resulting in an acceleration of zero. Mathematically an… … Wikipedia
Proper velocity — η.In flat spacetime, proper velocity is the ratio between distance traveled relative to a reference map frame (used to define simultaneity) and proper time τ elapsed on the clocks of the traveling object. It equals the object s momentum p divided … Wikipedia
