There is an old saying that any landing you can walk away from is a good landing. There is a lot of truth to this statement, especially if you are the one walking away. Here are the stories of two such landings that I am personally familiar with. Since they are both very similar in nature, they will be discussed simultaneously in the pages to follow. N9KF was a Model 1 Kitfox. It was built and flown by my father. The Kitfox is an experimental, homebuilt kit plane. Every plane, like every person, has a story. This is the story of N9KF or at least the story as I know it.
NEWTON'S LAWS - A Brief Review
Newton's First Law
An object remains at rest/motion unless an external force acts upon it.(Newman)
Newton's Second Law
The acceleration of a body or object is directly proportional to the net force acting on the body or object and is inversely proportional to its mass. (F=ma)(Newman)
Newton's Third Law
For every action force, there is an equal and opposite reaction force.(Newman)
Forces of Flight
LIFT
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)
Newton's third law, stated above, explains how the remaining lift force is produced. Lift is generated when the air hits and is deflected off of the underside of the wing. This deflection of air downwards, in turn, causes an upward lift force on the wing since there must be an "equal and opposite reaction force."(Newman) This force accounts for a relatively small portion of the total lift generated for a wing.(JEPPESEN 1-13)
WEIGHT
Weight is one of the opposing forces to lift. From Newton's second law, the weight of an object is the magnitude of the force of gravity on that object.
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 –
On November 28, 2004 at about 10:00 a.m. mountain standard time, a Canadair (now Bombardier) CL-600-2A12 (Challenger 600), tail number N873G, crashed into the ground during takeoff at Montrose Regional Airport (MJT), Montrose, Colorado. The aircraft was registered to Hop-a-Jet, Inc., and operated by Air Castle Corporation doing business as Global Aviation. (Insert Here)The flight was operating under Part 135 Code of Federal Regulations. The captain filed the flight under an IFR Flight plan. Of the six passengers on board, three died from fatal injuries and the other three sustained major injuries. The aircraft was totaled due to the impact with the ground and a post-crash fire.
Give a brief summary of the reading. What event was it describing and how was it analyzing that event?
This equation shows that mass will not affect the speed of an object, proving that whatever the mass of an object, the speed will always remain the same if all the other factors are kept constant.
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.
In this inquiry the relationship between force and mass was studied. This inquiry presents a question: when mass is increased is the force required to move it at a constant velocity increased, and how large will the increase be? It is obvious that more massive objects takes more force to move but the increase will be either linear or exponential. To hypothesize this point drawing from empirical data is necessary. When pulling an object on the ground it is discovered that to drag a four-kilogram object is not four times harder than dragging a two-kilogram object. I hypothesize that increasing the mass will increase the force needed to move the mass at a constant rate, these increases will have a liner relationship.
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.
The acceleration of a body or object is directly proportional to the net force acting on the body or object and is inversely
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.

First off, while Joe is in the plane, he does not constantly accelerate downward, assuming the altitude of the plane remains constant. Why might this be the case? Newton's Second Law states, "The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass" ...
When I stepped into the large neatly organized white polished plane, I never though something would go wrong. I woke up and found myself on an extremely hot bright sunny desert island filled with shiny soft bright green palm trees containing rough bright yellow hard felt juicy apples. The simple strong plane I was in earlier shattered into little pieces of broken glass and metal when crashing onto the wet slimy coffee colored sand and burning with red orange colored flames. After my realization to this heart throbbing incident I began to run pressing my eight inch footsteps into the wet squishy slimy light brown sand looking in every direction with my wide open eyes filled with confusion in search of other survivors. After finding four other survivors we began moving our small petite weak legs fifty inches from the painful incident. Reaching our destination which was a tiny space filled with dark shade blocking the extreme heat coming from the bright blue sky, I felt my eyelids slowly moving down my light colored hazel eyes and found myself in a dream. I was awakened the next day from a grumbling noise coming from my empty stomach.
If a force acts on a body, the body accelerates in the direction of the force. In the example of the force of gravity, small things like textbooks are pulled downward toward the center of the large mass of the Earth, not up into space, even if some people think that this might happen. Isaac Newton was the first to conceive of weight as the gravitational attraction. between the body and the Earth. The force that results from the gravitational attraction of the Earth on its surface is what we call weight. Science has chosen to measure the mass of objects in units that are roughly equivalent to the weight of those objects on Earth.
The second law is, “the relationship between an objects mass (m), its acceleration (a), and the applied force (f) is F= ma.” The heavier object requires more force to move an object, the same distance as light object. The equation gives us an exact relationship between Force, mass, and acceleration.
Lifter is a machine constructed to lift the weight & object. It also use to move the loads from one place to another place. It is constructed by using various channel section which support the main lifting mechanism. lifter can be operated using various types power sources like
