how could the air push on surface?
Answers
Answer:
Explanation:As it flies, a plane is in the center of four forces. Lift (upward force) and thrust (forward push, provided by a propeller) get a plane into the air. Gravity and drag (air resistance, which is friction caused by air rubbing against the plane) try to pull the plane down and slow its speed.
Answer:
we know that air occupies space although we can compress it.
it therefore requires space to move. if a surface is blocking its path,the air will apply pressure on the surface.
in other words air will push the surface.
Eg: when we put a paper sheet in front of a table fan and switch on the fan,it will fly away.
with this we can observe that the air is applying force on the paper and is thus pushing it away from its path.
