Air resistance

Moving objects like aircrafts, cars and arrows experience air resistance when they are in motion. Frictional forces of the air against the moving object cause this resistance. There is more (bigger) resistance with faster movement, and less resistance with slower resistance.
air resistance
Cars, aeroplans and many fast moving objects are usually streamlined to overcome resistance.

Have you seen bike riders in a race? They wear smooth clothing and helmets designed to overcome resistance. This makes them glide through the air with top speed.
