Aerodynamics was founded by a Sir George Cayley in the years of 1809-1810. This science was constructed by the principle of lift, drag, thrust, gravity. This theory was all depending on the science of physics. The uses of aerodynamics spread from automobiles to sports to birds. The most popular uses of aerodynamics is aircraft and cars. Aerodynamic was founded by Sir George Cayley. The most popular uses of aerodynamics is aircraft and cars. Drag, lift, thrust, gravity and the science of physics are all needed in the basics of the science of aerodynamic in aircraft and cars.
Sir George Cayley was born in December 27, 1773, Scarborough, Yorkshire, Eng. Died December 8, 1854, Brompton, Yorkshire. He was the father of the principle of aerodynamics.

Lift is an aerodynamic force perpendicular to the air flow. Drag is an aerodynamic force the acts as a parallel to the direction of the wind flows or against the flow of movement of the object. Thrust is the force that moves an object forward or the opposite of the force of drag. Gravity is the force of which keeps objects from floating to oblivion and beyond. The two primary aerodynamics forces are drag and lift. Drag is an aerodynamic force the acts as a parallel to the direction of the wind flows or against the flow of movement of the object. Lift is an aerodynamic force perpendicular to the air flow. As air moves underneath and toward an object, lift can drive an object, lift drives the object upwards and drag is the complete opposite, it acts as a parallel to the direction of the flow of wind and pushes against the wind. The opposite of the drag is the forward force of thrust. The account of weight is created by the force of the gravity pulling any and all objects towards the earth. The fundamentals of aerodynamics are the principles of drag, lift, gravity, thrust, and weight which is created by …show more content…
Though the aircraft is a more used example the automobile has many of the same principles of drag, lift, gravity, thrust, and weight which is created by gravity. If an automobile was on a race track with no created wind or wind at all would go faster than with wind because it would not have any drag. That is why NASCAR drivers go in a line or stay behind one or others there is no wind to produce drag to go faster. Automobiles started using aerodynamic body shapes in the early part of their history. As engines became more powerful and cars became faster, automobile engineers realized that wind resistance significantly hindered their
Now To talk about the forces that allow the car to move. There are two main aerodynamic forces acting on any object moving through the air. Lift is a force that acts 90° to the direction of travel of an object. Usually we think of lift when we think of an airplane. The plane travels forward (horizontally), and lift acts 90° to that motion of travel –

The Invention of Wings by Sue Monk Kidd is an amazing book that follows the lives of some very amazing women. Kidd shows what it meant to be a slave and what it meant to be a woman. This book mostly deals with slavery and how it affects people who are slaves, how they suffered but also how it affected people who were against slavery and trying to change the world. Kidd also covers sexism and what it means to be a woman with ambition, drive and wanting to be a woman who abolishes slavery. This book mainly follows the life of Sarah Grimke, a girl with drive, ambitions, and ideas; but who is also the daughter of a slave owning judge who lives in Charleston.
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.
Drag is caused by the disrupted air immediately behind an object moving through fluid/air. It acts perpendicular to and in the opposite direction of travel of the object and impedes the motion of the object. It would make sense that if the drag is minimized, the object will travel farther. Lift or curve in the motion of an object through air is a phenomenon that is noticeable in a ball traveling through fluid/air. This change in direction is due to the effect that spin has on the object in motion.
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.
What is aerodynamics? The word comes from two Greek words aerios concerning the air, and dynamis, meaning powerful. Aerodynamics is the study of forces and the resulting motion of objects through the air. Humans have been interested in aerodynamics and flying for thousands of years, although flying in a heavier-than-air machine has been possible only in the last hundred years. Aerodynamics affects the motion of a large airliner, a model rocket, a beach ball thrown near the shore, or a kite flying high overhead. The curve ball thrown by big league baseball pitchers gets its curve from aerodynamics.
In order to have a fast and efficient car all these things I have discussed need to be taken into consideration. A fast car should be designed with aerodynamic surfaces for a balance of maximum production of downforce and minimum drag creating surfaces. It should have as small an engine as possible to reduce mass and reduce the necessary size of the frontal area, but a large enough engine to be able to produce enough horsepower to be able to create more force than the resistance the car faces to accelerate and enough to balance with those forces at high speeds. The tires should be wide enough for fast acceleration and good cornering but not so wide it creates large amounts of rolling resistance. Your overall best example of such a car would be formula one races or Indy cars because they have to have good handling, fast acceleration and reach and maintain high speeds.
All flight is the result of forces acting upon the wings of an airplane that allow it to counteract gravity. Contrary to popular belief, the Bernoulli principle is not responsible for most of the lift generated by an airplanes wings. Rather, the lift is created by air being deflected off the wings and transferring an upward force to those wings.

George Gascoigne was born in 1539 in Cardington, United Kingdom as the son of Sir John Gascoigne. His father was a landowner and a successful farmer. George is said to have been educated at Trinity College in Cambridge. George’s life ended up being full of mishaps and he ended up going to prison for his debt, He tried to farm like his father and was very unsuccessful. George and his
This paper is a look at the physics behind car racing. We look look at how we can use physics to select tires, how physics can help predict how much traction we will have, how physics helps modern cars get there extreme speed, how physics lets us predict the power of an engine, and how physics can even help the driver find the quickest way around the track.
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.
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.
Here, we can use the vectors to use the Pythagorean Theorem, a2 + b2 = c2, to find the speed and angle of the object, which was used in previous equations.
