This slows the object down. Resistance in air and water is a type of frictional force that is also known as drag. Objects with a large surface area can produce more drag. The faster an object ...

This is where the drag coefficient — which measures how well a vehicle cuts through the surrounding air — comes into play.

The force is due to friction between the air and the exposed surfaces of the rider and bicycle. At high speed, this drag force can be the most importance source of resistance, and with a wind blowing, ...

The Bloodhound supersonic car will use a parachute's drag and air resistance to slow it down from 1000 mph. But what design makes the best parachute? Children from Links Primary School in London ...
