By making it more streamlined and aerodynamic
aerodynamic.
Aerodynamics help reduce drag so the engines can produce thrust.
1. Increase the angle of inclination. (of the slide) 2. Reduce drag (in air) by for eg: lying down, wear a streamlined suit/ helmet. 3. Introduce a lubricant and/or materials to reduce the coefficient of friction. 4. increase your launch velocity.
they wear a swim cap to reduce drag
It lowers the air resistance, which lets them go faster.
Because they have a death wish. Always wear a helmet. ALWAYS.
Road cyclists prefer tight fitting lycra. Low air drag and it's good at wicking sweat away from the body. MTBers often prefer more loose fitting clothing that offers more protection against whipping branches and falls.
In UK a motorcyclist must wear a helmet - not sure about cyclists or horse riders
don't drag it copy and paste it
Tight clothes, unless you Usain Bolt.
it doesn't
By streamlining the aircraft.
Drag is caused when there's resistance.... you vs. the wind. To reduce drag, wear tight clothing. Ever noticed how swimmers wear the tightest swimsuits they can, and put their hair in a cap? It's to keep the water from catching on their suit or hair. That's drag. The same is true for walking, running, or biking (although you'd look pretty foolish walking around in a swimsuit, of course!)
Kind of a loaded question for many but yes they should
to reduce drag
