Drag and Drafting - Science of Speed

The video explores the role of aerodynamics in NASCAR racing, focusing on concepts like drag and drafting. It explains how air affects race cars, the importance of reducing drag, and the techniques used to achieve this. The video also covers drafting, a strategy where cars drive closely to reduce drag and increase speed, and bump drafting, a more aggressive form of drafting. The video highlights the significance of these techniques at high-speed tracks like Daytona and Talladega.

How do rough surfaces and protruding parts of a car influence drag?

What strategies do drivers use to compensate for limited horsepower at tracks like Daytona and Talladega?

Describe the impact of bump drafting in NASCAR racing.
