Bernoulli’s Principle A Swiss scientist who was named Daniel Bernoulli in the 18th century discovered the Bernoulli’s Principle. Bernoulli (2009) stated that when the velocity of a gas or a liquid increases the pressure of the fluid would then decrease. This can be applied to many things, such as a plane or bird. Basically anything that uses wings to fly uses the Bernoulli’s Principle. Both birds and planes take an advantage of the Bernoulli the Bernoulli’s Principle. Flight (n.d.)[online] states that airplanes and birds have an airfoil shape. They have this shape in each of their wings and they are used to create lift. An airfoil shape has a certain shape that splits the air at the front part of the wing and it joins

Lift always require an airfoil. An airfoil uses the Bernoilli’s Principle. That is only part of what you need for lift. You also need an angle of attack. This the angle that is used for your flight. Different angles gives you different results. Some angle can give you lots of lift, but lots of drag, or an angle can give you almost no drag, but little lift. Lift and drag all depends on the shape of the wing, the speed, and the angle of attack. Most planes start out with an angle that has the forward edge that is raised, so it has a lot of lift, and has a good lift to drag ratio. Then it would probably have an angle that gives you less drag and no lift so it could fly and get to the location faster. Weight is another important force of the plane. It basically acts like the opposite of lift. Without weight, it would be hard to come back down to the ground. Airplane designers normally try to make the airplane as light as they can, so the plane can fly faster, and so lift could be created easier and with less drag. Britannica (2014) says that pilots must control the total weight of the plane at all times. This weight includes the passenger, fuel, baggages, etc. Distributing the weight of the plane is as important as the weight of the plane in
Simply put, the less weight your dragster has, the faster it will go. This is the most important factor that will figure into your design. Keep it light!
Bottle rockets are great models to examine Newton’s three laws of motion. The bottle rocket will remain on the ground until an unbalanced force, water, thrusts the rocket upward. This is defined by Newton’s first law of motion: an object at rest stays at rest or an object in motion, stays in motion (in the same direction/at the same speed) unless acted upon by an unbalanced force. It is also known as the law of inertia.
Wilbur Wright once said, “The desire to fly is an idea handed down to us by our ancestors who... looked enviously on the birds soaring freely through space... on the infinite highway of the air.” He changed American culture forever when he made the first flight alongside his brother Orville. This invention would have an even greater impact on our culture than cars. Although cars are used every day in America, planes have had the largest impact on American culture. Without planes, our lives would be drastically different, but not in a good way. Airplanes had a major impact on military, commerce, and travel.
They found that birds tilted their wings for balance and control, and tried to simulate this, developing a concept called “wing warping.” When they added a moveable rudder, the Wright brothers found they had the formula-on December 17, 1903, they succeeded in flying the first controlled flight of a power-driven airplane. Wilbur flew their plane for 59 seconds, at 852 feet, a crazy
First of all you will have to understand the principles of flight. An airplane flies because air moving over and under its surfaces, particularly its wings, travels at different velocities, producing a difference in air pressure, low above the wing and high below it. The low pressure exerts a pulling influence, and the high pressure a pushing influence. The lifting force, usually called lift, depends on the shape, area, and tilt of the wing, and on the speed of the aircraft. The shape of the wing causes the air streaming above and below the wing to travel at different velocities. The greater distance over which the air must travel above the curved upper surface forces that air to move faster to keep pace with the air moving along the flat lower surface. According to Bernoulli’s principle, it is this difference in air velocity that produces the difference in air pressure.
For a plane to create lift, its wings must create low pressure on top and high pressure on the bottom. However, at the tips of the wings, the high pressure pushes and the low pressure pulls air onto the top of the wing, reducing lift and creating a current flowing to the top. This current remains even after the wing has left the area, producing really awesome vortices.
As the air flows over the wing producing lift, it grabs onto the wings surface and causes drag. Drag can be measured by the equation D=Cd 1/2 (pV2)S, much like the lift equation. The drag coeficent Cd is found, again, by determining ...

Flight uses four forces: lift, weight, thrust, and drag. In a nutshell; so to speak, an airplane must create enough lift to support its own weight. Secondly, the airplane must produce thrust to propel itself. Finally, the aircraft must overcome the drag or the force of resistance on the airplane that is moving through the air. All four of these forces are vital and necessary for an aircraft to move, takeoff, fly, and land.
According to mechanical physics, a force is an effect that may cause a body to accelerate. Also as stated in Isaac Newton’s second law of motion, force is a vector quantity (has magnitude and direction) that is proportional to the product of the mass of a body and its acceleration.
Ever since I was little I was amazed at the ability for a machine to fly. I have always wanted to explore ideas of flight and be able to actually fly. I think I may have found my childhood fantasy in the world of aeronautical engineering. The object of my paper is to give me more insight on my future career as an aeronautical engineer. This paper was also to give me ideas of the physics of flight and be to apply those physics of flight to compete in a high school competition.
The basic concepts of lift for an airplane is seen. The air that is flowing splits to move around a wing. The air that that moves over the wing speeds up creating lower pressure which means that the higher pressure from the air moving slower under the wing pushes up trying to equalize the pressure. The lift generated can be affected by the angle at which the wing is moving into the flowing air. The more surface area of the wing resisting against the flow of air can either generate lift or make the plane dive. This can be easily simulated in everday life. Next time you are riding in a car with someone stick your hand out the window. Have your fingers pointing in the direction of the motion of the vehicle. Now move your hand up and down slightly. You can feel the lift and drag that your hand creates.
Lift is generated by the air flow around the plane's wing. This effect is explained mostly by Bernoulli's Principle which states that the pressure of the air decreases as the velocity of the air increases. The design of a plane's wing changes the airflow around the wing's surface. The air has farther to travel over the top of the wing than the air traveling below the wing. Therefore, the air traveling above the wing is traveling at a higher velocity than the air traveling below it. As air flows around the wing, a high pressure region with low air velocity is created below the wing, and a low pressure region with high air velocity is created above the wing. The difference between the two pressures generates the lift force. (JEPPESEN 1-11)
Sir Isaac Newton is the man well known for his discoveries around the term, Motion. He came up with three basic ideas, called Newton’s three laws of motion.
Projectile motion is the force that acts upon an object that is released or thrown into the air. Once the object is in the air, the object has two significant forces acting upon it at the time of release. These forces are also known as horizontal and vertical forces. These forces determine the flight path and are affected by gravity, air resistance, angle of release, speed of release, height of release and spin
