If you ran around in circles, your speed would be constant, but your velocity would be constantly changing. Your average velocity would be zero!

And so would your IQ.

Take that, track team.

Yep, that's precisely it. With velocity, direction is important, but with speed it is not.

If you ran around in circles, your speed would be constant, but your velocity would be constantly changing. Your average velocity would be zero!

OOoooh... I think I got it. speed = |velocity|

Havn't really had any of this yet, but you might find the answers there..
As far as I understand, velocity is a vector and speed is not..

Today my book asked for the average velocity of a function AND the average speed of a function. Huh? I thought velocity and speed were the same thing and would have bet my life on it!

Somebody please explain this madness.
