The forces involved in the flight of a JET are
DRAG, LIFT, GRAVITY and THRUST
UPTHRUST, BUOYANCY, GRAVITY, DENSITY
FRICTION, GRAVITY, ELASTIC, DENSITY
Bernoulli's Law states that
Air that moves always creates a region of HIGH pressure.
If the air is perfectly still an area of LOW pressure is created
Slow moving air always creates low pressure
Fast flowing air creates relative LOW pressure while slow moving air creates relative HIGH pressure
Newton's third law of motion is illustrated as the propeller spins to push the plane forward. Which comment is TRUE?
The propellar pushes air forwards which has the effect of sucking the plane forwards.
Newton's law does not apply to the way the propeller works
The heavier the propeller the better it works according to Newton's Law.
The propeller pushes air back which in turn pushes the plane forward with a force equal to that at which the air is pushed back.
