The position of two wings should be relative to each other as if they were very close then the resultant force will be in opposite direction and thus cancel each other. Two wings produce more down force as the lift coefficient increases and the drag decreases. Table 1. Calculated value of Air Resistance Determination of Air Resistance Air resistance is the resistance offered by air to the movement of a vehicle. The air resistance has an influence on the performance, ride and stability of the vehicle and depends upon the size and shape of the body of the vehicle, its speed and the wind velocity.
Flight simulator processor with about 1.0GHz [20] Additionally, in 2000, Theodore conducted a study on helicopter flight simulation dynamics. He proposed a coupled specific rotor with fuselage engineered flight simulator [12]. This flight simulator designed to provide requested training for the helicopter pilots. The helicopter flight simulator platforms should be designed sensitively as the training for
Lift “How can a heavy metal lift off the ground”? You may ask. The answer to this question is the lift of the wing, and there are two explanations about how the lift are generated. As everyone can see, the shape of the airplane wings is in a stream line form, which is flat along the bottom and curved on the top. The purpose of this design is not for pleasing to the eye, but for the perspective of physics.

Besides that, the pressure distribution along the pressure cylinder and aerofoil surface is also being measured. 2.0 Objective The following are the objectives of the experiment: * To study the factors directly affecting the lift, drag forces and pitching moment which includes: wind velocity, and angle of attack. * To differentiate the pressure distribution between the pressure cylinder and aerofoil. 3.0 Theory The shape of an aerofoil causes the air along the top surface to speed up resulting in a negative pressure and the air on the lower section slow down resulting in a positive pressure.
IBDP Physics Practice Lab - Factors Affecting the Drop Time of a Falling Body By Clevis Tam Aim: To investigate how the relationship of the terminal velocity of a falling parachute depends on the mass of the clay. Variables: • Independent Variables: The mass of the Clay (g) • Dependent Variables: The time the clay takes to reach the ground (s), The speed of the clay that is processed after collecting data (ms -1) • Controlled Variables: Method of releasing the clay, the area of the parachute Materials / Apparatus: 1. Meter Ruler (0-1m, measures to 0.001m) 2. Electronic Stopwatch (measures to 0.01s) 3. Drop Height (2.56m) 4.
Newton’s Second Law and the Work-Kinetic Energy Theorem October 13, 2010 Abstract This experiment utilizes an air track first as an inclined plane with the slider accelerating due to gravity and second as a level surface with the slider accelerating due to the pull of an attached free-falling object of known mass. In both cases, the Work performed is calculated based on formulas for mechanical work and for kinetic energy. The two results are compared. The first part yielded an average acceleration of 0.715 m/s2 (a 1.58% error) and the average result for the Work performed was 0.0204 N*m with only a 0.9% difference. The second part suffered critical errors due to improper data and the results are not significant or useful.
The key point is that when these two directions combined, this provides the chance to ski jumper to fly the farthest. Evaluation: Overall observations still permit me to draw a conclusion on the effects of different wind directions on the performance and results of ski jumper. However there are certain limitations of the experiment. Generally, random

Purpose: When light travels through different mediums, it is being refracted. The purpose of this lab is to test Snell’s law of refraction. Hypothesis: The angles of refraction that I predicted from the angle of incidences by using Snell’s Law are below on the predicted angle Column. To obtain these values I used the index of refraction of crown glass because it is more likely close to the glass (plexiglass) that we are using. Angle of Incidence 0° 10° 20° 30° 40° 50° 60° Predicted angle of refraction 0 6.56° 13.0° 19.2° 25.02° 30.27° 34.74° Variables and Controls: Independent Variable: The angle of the light coming from the ray box or the angle of incidence Dependent Variable: The angle of refraction on the plexiglass.
