Applications In Real Life
Air Flight:
- The way Bernoulli’s principle works in air flight is mainly because of the shape of the wings of the airplane. While the top part is partially curved, the bottom part is completely flat.
- This allows the air on top of the wing to flow faster while the air on the bottom of the wing travels slowly; both reach the tip of the wing at the same time. This creates lift.
- An airplane is also acted upon by a pull of gravity in which opposes the lift, drag and thrust. Thrust is the force that allows the airplane to move forward while drag is air resistance that opposes the thrust force.
- Baseball:
- 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. Which makes the bottom part of the ball to accelerate downwards faster than the top part.
- The same way that Bernoulli's principle works for creating lift in airplanes, it works for creating lift in sails.
- All sailboats have two parts to it: a sail which points north and a keel which points on the opposite direction. If the speed of the air increases on the sail, there is less pressure on the sail, and conversely there is less pressure on the keel but a higher speed.
- 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.
