resistance is useful when a plane is flying in the air, air resistance. it is also useful when a boat is floating on water, water resistance.
how can aerodynamics be used to reduce air redistence
You don't "resist" it but you "reduce" it. For example, many vehicles and projectiles are made in a streamline design to reduce air resistance.
by flying in the air
Reducing air resistance would give your car better gas mileage, and improve your time in speed skating, cycling, and downhill skiing, among many other sports.
It is useful to stop aircrafts when they land as air brakes and parachutes are used to stop the aircrafts
to reduce air resistance or drag.
To reduce air resistance.
Decrease the surface area of the object
To reduce air resistance or drag.
to reduce air resistance
Force streamlining reduces air resistance or air friction.
Cyclists bend forward to reduce air resistance.
By designing the car to be as streamlined as possible.
It tends to reduce air (or water) resistance.
By giving it a streamlined shape.
Aerodynamics is related to the shape of the car to reduce air resistance and drag. Aeroplanes are kept clean and polished for the same reason - to reduce the friction caused by the air resistance.
it cuts down air resistance.
It can slow you down because it is a frictional force
By moving in a vacuum. Other than that, basically you can't. You can reduce air resistance, by building vehicles so they have an aerodynamic shape - but you can't eliminate air resistance entirely, for any moving object.
no, the reverse, you will increase it
