It would be a speed, not a velocity, because velocity is a vector not a scalar. Something like "10000 km/year in a north east direction" is a velocity.
But with that corrected, 10000 km/year certainly is a speed; it's just an average speed rather than an instantaneous speed.
- toxik 5y agoNo. It’s car use accumulated over a year. It is not an average speed. I don’t agree that there is a wide consensus that velocity must be a vector outside of physics where it actually matters. “High velocity” is a term that does not hinge on a vector being present somehow.
- jaclaz 5y agoNot only, IF it was a speed (it isn't) it would be a very, very slow one, as 10,000/(365x24)= 1.14 km/h.
- toxik 5y agoYes right, and a completely meaningless quantity without saying it’s the average /over a year/, so the accumulation interval is essential - thus cannot be thought of as a speed or velocity.
- sudosysgen 5y agoIt's definitely average speed over a year. High velocity refers to the magnitude of a vector beyond 2D, so there is no conflict here.
