Wait, I thought speed was a scalar quantity and therefore doesn't have any directional value. If this is so, why would the speeds cancel out?
If we are in fact using velocities, why is it called the rms SPEED?
Thanks
Sorry for my immature grasp of mathematics, but I don't understand why finding the mean of the velocity squared will not "cancel" the velocities in the first place.
Do you mind elaborating on this.
thanks
We've just learned about kinetic theory and gases and my teacher showed us the rms speed. He himself doesn't know why its called the rms speed, or how it originated and I was curious to find out myself. Why go through all the trouble when you could just say the average speed?
If anyone could...
