Welcome to Rocket Research 103

"Kind of a Drag"

Now that you’ve completed Rocket Research 101 and 102, you should have a good basic rocket design. But there is another factor you must consider. In order to maximize its performance, you want the rocket to have as little wind resistance, or “drag,” as possible.

Why? Write down two advantages of having a rocket with low air drag.

All set? Check your answers here.

The shape of an object plays a key role in how much drag it experiences while moving through the air (or any fluid, for that matter). Check this page for a good review of drag and the effects of different shapes on drag.

Let's conduct some experiments to better understand drag.
