Airplanes are very heavy, so it may seem strange that they are able to lift off of the ground and fly. Flight is possible because of a balance of four different physical forces, which are lift, drag, weight, and thrust.
Lift and weight balance each other, and thrust and drag have to be present in just the right amounts. Sir Isaac Newton studied math and science, and he discovered three laws of motion that explain a lot about how things move.
Isaac Newton was born on Dec. Newton lived with his grandmother as he was growing up, and he attended Trinity College of the University of Cambridge. As he was attending college, he began studying math and science. He was very interested in math and physics, and he started writing down some of his ideas about motion and gravity. His ideas about math led to the invention of calculus, which made it possible for people to solve complicated math problems.
Newton also studied white light, and he discovered the color spectrum. Newton published a science book in that included his three laws of motion. Newton worked so hard on his science studies that Queen Anne made him a knight in Newton died inwhen he was 84 years old. A force is either a push or a pull. The law also states that a moving object will keep moving in the same direction and at the same speed unless a force changes this.
An easy way to think about this law is to remember that things will keep doing what they are doing unless something causes that to change. This law states that heavier objects need more force to make them move faster or to change the direction they are moving in.
The bigger the force, the more acceleration will happen. The third law of motion states that every action has an equal and opposite reaction. Scientists sometimes call this interaction between forces an action-reaction pair. This means that when you want to slow down or stop a moving object, you have to apply a force to it in the opposite direction that it is moving. The physics of flight requires that lift, drag, weight, and thrust happen at the correct time and in the proper amounts.
For an airplane to go up into the air, the lift has to be stronger than the force of gravity. Lift happens at the wings as air passes over them. Airfoils in the wings make the air move over the tops of the wings faster than it moves across the bottoms of the wings.

This subject keeps coming up in the discussions and questions such as this one, which asks if lift equals weight in level flight. Good answers there, pointing out that upwards force has many sources. Koyovis Why would a glider have water ballast? If it is trying to stay aloft without an engine, wouldn't it be better to be as light as possible? So I was looking at the description of a ASW 27 B glider and ran across this statement: Two water tanks in the wing plus a further 35 liter tank in the fuselage enable the ASW 27 B to carry more Lnafziger What produces thrust along the line of flight in a glider?
After reviewing discussions and vector diagrams of gliders in flight, the vertical lift component and the vertical drag components seem to produce a steady state, 0 acceleration balance with gravity. Robert DiGiovanni 7, 1 1 gold badge 9 9 silver badges 36 36 bronze badges. What is the relation between an airplane's altitude and the drag it is experiencing? What is the actual air speed over and under a wing due to Bernoulli's Principle?
Bernoulli's Principle states that as a fluid speed increases, its pressure decreases, and vice versa. Air flowing over the wing of an aircraft flows faster than its neighboring air flowing under the Erich 3, 1 1 gold badge 20 20 silver badges 51 51 bronze badges. Do any airplane designs exist that don't involve a flight surface that provides downforce?
Most aircraft maintain longitudinal stability by balancing three forces: The down force acting through the center of gravity CG The lifting force acting through the center of lift The down force Descending on a given glide slope e.
ILS at a given airspeed— is the size of the lift vector different in headwind versus tailwind? We had a discussion with friend and we were talking about if the airplane is on approach and the one is landing with tailwind and the other one is landing with headwind, so both have the same value of Is excess lift or excess power needed for a climb?
As answered in this question, aircraft need excess power - not excess lift - to climb. This is plausible when the aircraft's thrust vector has a vertical component its nose and engine points upwardsChris 1 1 gold badge 8 8 silver badges 9 9 bronze badges.Author by : E. Modern aviation has been made possible as a result of much scienti c - search. However, the very rst useful results of this research became ava- able a considerable length of time after the aviation pioneers had made their rst ights.
Apparently, researchers were not able to nd an adequate exp- nation for the occurrence of lift until the beginning of the 21st century.
Also, for the fundamentals of stability and control, there was no theory available that the pioneers could rely on. Only after the rst motorized ights had been successfully made did researchers become more interested in the science of aviation, which from then on began to take shape.
In modern day life, many millions of passengers are transported every year by air. People in the western societies take to the skies, on average, several times a year.
Especially in areas surrounding busy airports, travel by plane has been on the rise since the end of the Second World War. Despite becoming familiar with the sight of a jumbo jet commencing its ight once or twice a day, many nd it astonishing that such a colossus with a mass of several hundred thousands of kilograms can actually lift off from the ground.

Sir Isaac Newton and the Physics of Flight
Not a review, it's the only physics book geared for aviation training that uses every day examples to explain every facet of the subject. Author by : David W. This practical guide is the most intuitive introduction to basic flight mechanics available. Understanding Flight, Second Edition, explains the principles of aeronautics in terms, descriptions, and illustrations that make sense--without complicated mathematics. Updated to include helicopter flight fundamentals and aircraft structures, this aviation classic is required reading for new pilots, students, engineers, and anyone fascinated with flight.
Understanding Flight, Second Edition, covers: Physics of flight Wing design and configuration Stability and control Propulsion High-speed flight Performance and safety Aerodynamic testing Helicopters and autogyros Aircraft structures and materials. Author by : Charles E. From the basics of forces and vectors to craft-specific applications, this book explains the mechanics behind the pilot's everyday operational tasks. The discussion focuses on the concepts themselves, using only enough algebra and trigonometry to illustrate key concepts without getting bogged down in complex calculations, and then delves into the specific applications for jets, propeller crafts, and helicopters.
FAA-aligned questions and regulatory references help reinforce important concepts, and additional worked problems provide clarification on complex topics. Modern flight control systems are becoming more complex and more varied between aircrafts, making it essential for pilots to understand the aerodynamics of flight before they ever step into a cockpit.
This book provides clear explanations and flight-specific examples of the physics every pilot must know. Review the basic physics of flight Understand the applications to specific types of aircraft Learn why takeoff and landing entail special considerations Examine the force concepts behind stability and control As a pilot, your job is to balance the effects of design, weight, load factors, and gravity during flight maneuvers, stalls, high- or low-speed flight, takeoff and landing, and more.
As aircraft grow more complex and the controls become more involved, an intuitive grasp of the physics of flight is your most valuable tool for operational safety. Flight Theory and Aerodynamics is the essential resource every pilot needs for a clear understanding of the forces they control. Author by : United States Naval Academy.
Are those bumps and noises normal? Why are some take-offs delayed?Mini Physics. The following article is about the physics behind the flight of airplanes. There are no equations in this articles. Source: Yahoo Associated Content. It was faith in physics that reassured the engineers and bankers that such a massive undertaking was worth the risk. Physics describes four basic elements involved with flying an airplane.
Flight involves a constant tug of war between lift vs. The physics describing lift was established hundreds of years before such a machine would fly. Sir Isaac Newton and Mr. Bernoulli unknowingly played key roles in aviation.
Simply put, a gas will accelerate if it is forced to pass through a constriction. There must be a drop in pressure associated with this acceleration. Early aviation designers understood and applied this relationship to the wings of aircraft. Airflow travelling above a curved wing will accelerate and travel faster than the airflow beneath the wing.
The lower pressure zone created above the wing, coupled with pressure beneath the wing, provides lift. According to my FAA Handbook, the air pressure pushing the wing upwards from beneath exceeds the vacuum force lifting the top surface. Sir Isaac Newton stated that for every action there is an equal and opposite reaction. Application of this law is even more important to flight. In aviation the force involved is the movement of air against the wings and control surfaces.
You will notice that many aircraft have the wing mounted at a slightly upturned angle. This built in angle ensures air is constantly pushed down by the wing. As always, there can be too much of a good thing. The physics that caused the aircraft to fly no longer applies if the wing stalls completely.
Airplanes are controlled by the elevator, rudder and ailerons.Mini Physics. The following article is about the physics behind the flight of airplanes. There are no equations in this articles.

This built in angle ensures air is constantly pushed down by the wing. As always, there can be too much of a good thing. The physics that caused the aircraft to fly no longer applies if the wing stalls completely. Airplanes are controlled by the elevator, rudder and ailerons. The angle of attack Newton and the change in pressure Bernoulli both act to direct the aircraft in the desired direction. Various types of flaps are used to increase lift for landings and takeoffs.
These force more air downward and increase the pressure difference on the wing. Physics describes the performance of propellers and helicopter rotors in precisely the same manner. The force of gravity on the Earth is measured to be 9. An aircraft must overcome this force to get airborne. To be of any use it must also lift passengers, fuel and cargo.Turbulence: one of the great unsolved mysteries of physics - Tomás Chor
Weight reduction has always been paramount in aviation and will remain so unless anti-gravity technology is developed. Boeing is seriously exploring the possibility of using spinning super conductors to reduce the effects of gravity on aircraft. The physics of lift is quite useless without thrust. The development of jet engines allowed enormous increases in weight and speed.
Jet engines gas turbines can deliver tens of thousands of pounds of thrust but have voracious appetites for fuel. A wise combination of gas turbine and conventional propeller delivers large thrust in a more economical albeit noisy manner.
