24. How does drag vary with speed

Edited on Tue May-27-08 10:24 AM by hokies4ever

Is it linear? (hint: the answer might be no)

Drag is not linear with speed, plain and simple. Surely you can find an equation for the drag in your physics book, right? Does it vary linearly with speed? Nope. And if you don't like that theory, then do wind tunnel tests for cars show that drag varies linearly with speed?

You do understand why increasing speed when you're in the highest gear, taking into account the fact that drag does not increase linearly with speed, means that you'll get a lower gas mileage, right?
