Analysis: Models of air resistance

Here you’ll learn some fluid mechanics – another strand of Engineering Mechanics.

There is much to understand here, but you can gain a lot without going into detail. So we’ll quote equations and provide just enough background for you to be able to use them and appreciate their implications.

Data from the experiment are given in the Downloads section below.
