One component of this quantity is equal to the direction of motion, while the other is generally equal to distance over time.
In astronomy, the variation in this quantity at different galactic radii makes up a rotation curve. According to the virial theorem, this quantity is equal to the square root of big G times mass over radius. One form of this quantity is inversely related to the square root of a fluid's density times an object's area times the drag coefficient. The magnitude of the centripetal acceleration is equal to this quantity squared over the radius. One component of this quantity is equal to the direction of motion, while the other is generally equal to distance over time. For 10 points, name this vector whose magnitude is equal to speed.
