ORIGINAL: Raechard quote:
ORIGINAL: Lumus What... ...is the airspeed velocity of an unladen swallow? This question is a bit misleading in some respect because velocity and speed are more or less the same. The difference as I recall is that with speed you travel a distance but with velocity your overall distance travelled may be zero. e.g.. in the case of something travelling in a circular trajectory. So the addition of the term velocity after airspeed isn’t required in this instance and makes the question appear more complicated than it is. Wrong, Velocity would be a measure of speed with referance to something "thought of" as stationary, say the ground for instance. Airspeed (from a pilot) is your speed relitive to the moving airmass around you. For example a plane moving over the ground at a velocity of 250 miles per hour; with a tail wind of 10 miles per hour would have an airspeed of 240 miles per hour. The same plane with a 10 mile per hour head wind would have an airspeed of 260 miles per hour.
