FOR LANDING THRUST MUST BE LESS THAN DRAG, AND LIFT MUST BE LESS THAN WEIGHT. THE FOUR FORCES ACTING ON AN AEROPLANE AN AIRPLANE IN FLIGHT IS THE CENTRE OF A CONTINUOUS TUG OF WAR BETWEEN FOUR FORCES: LIFT, GRAVITY FORCE OR WEIGHT, THRUST, AND DRAG. LIFT AND DRAG ARE CONSIDERED AERODYNAMIC FORCES BECAUSE THEY EXIST DUE TO THE MOVEMENT OF THE AIRCRAFT THROUGH THE AIR. THE WEIGHT PULLS DOWN ON THE PLANE OPPOSING THE LIFT CREATED BY AIR FLOWING OVER THE WING. THRUST IS GENERATED BY THE PROPELLER AND OPPOSES DRAG CAUSED BY AIR RESISTANCE TO THE FRONTAL AREA OF THE AIRPLANE.
1.) What is lift and how is it developed over a typical airfoil? Be sure to address both applicable theorems, and how each contributes to the development of lift. Additionally, compare and contrast symmetrical and cambered airfoils and how the development of lift varies over each one. Be sure to address the concepts of center of pressure and aerodynamic center, as well as any pitching moments occurring on the airfoils Lift is the force that directly opposes the weight of the airplane.
Vary m by adding or removing mass from the glider. Repeat steps 5-11. Try at least four different values for m. Calculations For each set of experimental conditions: Use the length of the glider and your average times to determine v1 and v2, the average glider velocity as it passed through each photogate. Use the equation a = (v2 - v1)/t3 to determine the average acceleration of the glider as it passed between the two photogates. Determine Fa, the force applied to the glider by the hanging mass.
Jet engines move the airplane forward with a great force that is produced by a thrust and causes the plane to fly very fast. A jet engine operates on the application of Sir Isaac Newton's third law of physics which states that for every action there is an equal and opposite reaction and propulsion. Propulsion means to push forward or drive an object forward. A propulsion system is a machine that produces thrust to push an object forward. Thrust generated depends on the mass flow through the engine and the exit velocity of the gas This law is demonstrated in simple terms by releasing an inflated balloon and watching the escaping air propel the balloon in the opposite direction.
For most purposes Newton's laws of gravity apply, with minor modifications to take the general theory of relativity into account. 2. Inertia - A property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force. 3. Potential Energy - Is the energy stored in an object due to its position in a force field or in a system due to its configuration.
And if they have mass, they have inertia. That is, an object in space resists changes in its state of motion. A force must be applied to set a stationary object in motion. Newton's laws rule - everywhere! 5.

Which of the following objects is not accelerating? a. the space shuttle as it is orbiting Earth b. a car turning a corner c. the space shuttle when it is being launched d. a bike moving in a straight line at a constant speed 3.
There’re six gears on a motorcycle. The gear lever is a stationary lever. It will toggle up or down and will retract in the original position. Pushing the gear towards the ground is first gear. The next gear up in neutral.
Next you want to see how it runs at high speeds. Do the brakes work, how straight is does it travel. Are you getting too much air trapped? This is called the parachute affect. You want to make sure that the wheels are properly aligned.
NASA has greatly influenced our field of computer technology. They have helped with things in this area such as: Virtual Reality and the Air Quality Monitor. Virtual Reality allows a person to enter a computer generated environment. Also the simulation moves with your head movement and is combined with a Stereo viewing device wich creates the ultimate experience. The Air Quality Monitor seperates different gasses in smokestacks and determins the amount of gases present so as to meet the smokestack emission requirements.
