Description

A cyclist is used as an example to explain what air resistance is. Drag is mentioned. Two ways to reduce air resistance are stated: reducing the area in contact with air (by the cyclist ducking down or cycling behind someone else) and by being more streamlined (wearing smoother surfaces or a more streamlined helmet).
