This is a short overview (goals, exercises) about combining the topic of friction (with air or due to using brakes) with the practice of cycling.
Students describe un-/desired types of friction in cycling and methods of de-/increasing them.
- letting the bicycle roll (after reaching a certain speed or just down a slope) while trying different poses to reduce air resistance (attach an umbrella on the rear end?)
- driving on different surfaces (asphalt, soil, sand, …)
- After reaching a specific speed, stop the bike by a) braking b) just letting it roll c) using oiled brakes
