Drafting to Save Energy: Air Resistance Explained
When a vehicle moves fast, it leaves a low-pressure wake of turbulent air behind it. Competitors in events like the Tour de France ride closely in this pocket, reducing their own air resistance by up to 40 percent and conserving vital energy.
The great fall: gravity versus air
Terminal velocity: the speed limit of falling
Catching the wind: the art of the parachute
Slicing the sky: cheating drag on the ground

artiteacher Deploy parachutes and tilt wings to discover how air resistance controls terminal velocity.
Kingfisher train: The nose of Japan's Shinkansen bullet train was modeled after a kingfisher's beak to stop loud sonic booms when entering tunnels.
The shaping of an object to reduce aerodynamic drag as it moves through a fluid. In 1997, the streamlined ThrustSSC became the first land vehicle to break the sound barrier.
Which bird's beak inspired the aerodynamic redesign of Japan's Shinkansen bullet train?
What is the name of the system in Formula 1 that flattens the rear wing to reduce drag?
Which natural shape is considered the most aerodynamic, with a drag coefficient of 0.04?
