Velocity of propagation — (VoP) or velocity factor (VF) is a parameter that characterizes the speed at which an electrical signal (e.g. radio) passes through a medium. Expressed as a number between 0 and 1 (or a percentage), it is the ratio of a signal s transmission… … Wikipedia
Velocity — In physics, velocity is defined as the rate of change of position. It is a vector physical quantity; both speed and direction are required to define it. In the SI (metric) system, it is measured in meters per second: (m/s) or ms 1. The scalar… … Wikipedia

Root mean square — In mathematics, the root mean square (abbreviated RMS or rms), also known as the quadratic mean, is a statistical measure of the magnitude of a varying quantity. It is especially useful when variates are positive and negative, e.g., sinusoids.It… … 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
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
Inverse-square law — In physics, an inverse square law is any physical law stating that some physical quantity or strength is inversely proportional to the square of the distance from the source of that physical quantity. Areas of application In particular the… … Wikipedia
