Quick stream = low air pressure
Slow stream = High air pressure
Draw the air currents.Standing Tennis Ball
The tennis ball is surrounded by an air stream of equal speed, thus equal pressure.
The down force is ‘G.’
Thus, the ball stands on
air. The air pressure below
is equal with the ‘G’ force.
surface pressure is exerted on what
surface areas of the wing. Is this
plane ascending or descending?
pressure around specific areas of the
wing. Again, notice that the low pressure
region is above the wing, allowing for
What forces are =?
