AIR FLIGHT
 One of the most common everyday applications of Bernoulli's principle is in air flight. The main way that
Bernoulli's principle works in air flight has to do with the architecture of the wings of the plane. In an airplane wing,
the top of the wing is somewhat curved, while the bottom of the wing is totally flat. While in the sky, air travels
across both the top and the bottom concurrently. Because both the top part and the bottom part of the plane are
designed differently, this allows for the air on the bottom to move slower, which creates more pressure on the
bottom, and allows for the air on the top to move faster, which creates less pressure. This is what creates lift,
which allows planes to fly. An airplane is also acted upon by a pull of gravity in which opposes the lift, drag and
thrust. Thrust is the force that enables the airplane to move forward while drag is air resistance that opposes the
thrust force

BASEBALL
Baseball is an example of where Bernoulli's principle is very visible in everyday life, but rarely do most people actually take note of
it. One example in baseball is in the case of the curve ball. The entire pitch works because of Bernoulli's principle. Since the stitches of
the ball actually form a curve, it is necessary for the pitcher to grip the seams of the baseball. The reason as to why this is a necessity
is that by gripping the baseball this way, the pitcher can make the ball spin. This allows for friction to cause a thin layer of air to engulf
the misunderstanding of the baseball as it is spinning, but since the ball is spinning in a certain manner, this allows for more air
pressure on the top of the ball and less air pressure on the bottom of the ball. Therefore, according to Bernoulli's principle there
should be less speed on the top of the ball than there is on the bottom of the ball. What transpires is that the bottom part of the ball
accelerates downwards faster than the top part, and this phenomenon allows for the ball to curve downward, which causes the
batter to miscalculate the ball's position.
.
STANDING TENNIS BALL
 Why the tennis ball ‘stands’ in the air?
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
‘G’

AIR FLOW
Race cars
Notice the shape of the spoiler. The spoiler starts out thin and
gradually curves upward. This causes the velocity to decrease and pressure
to increase on the top. Racecars designs use Bernoulli’s principle to keep the
car on the ground, and allow the car to make sharper turns.
The spoiler of the car is shaped so that the velocity of air on
the top of the spoiler is moving slower, thus creating more pressure on the
top of the car pushing the car downward. The velocity of air on the bottom
of the spoiler is much faster, thus having less pressure pushing upward on
the car.
