In terms of impulse and momentum why is it important that helicopter blades deflect air downward?
Wiki User
∙ 12y ago
The blades impart a downward impulse to the air and produce a downward change in the momentum of the air. The air at the same time exerts an upward impulse on the blades, providing lift. (Newton's third law applies to impulses as well as forces.)

Can wind deflect a bullet?
In the strictest definition of the word deflect, yes it can. However, it might be more correct to say that the wind can affect the trajector and path of a bullet.
Why is it important that helicopter blades deflect air downward?
Think of it like this if you blow on a thin peice of paper from the bottom it would go up but if you were to blow on it from the top then it would go down. So when the blades on a helicopter rotate it creates air resistance below it there fore making it easy for it to fly.

What keeps aeroplanes in the sky?
The wings of the plane keep the plane in the sky.The wings deflect air downward. As described by Newton's 3rd law of motion, this causes an upward force on the wing, and therefore on the airplane as a whole, keeping it aloft.Note that a source of energy is required to keep the airplane moving forward, and therefore making the wings deflect air downward. In powered flight, this energy source is the engine(s). However, a glider stays aloft by trading some amount of altitude, and therefore gravitational potential energy, for forward motion and the consequent lift.

Why do they make bowling balls so darn heavy?
Momentum. A knowledgeable bowler knows that the ideal form requires no muscle to hold onto the ball (think of swinging a bucket full of water). The heavier the ball, the more pins it knocks down. Lighter balls tend to deflect to the side.
