will travel. This is accomplished by the quarterback throwing the football over handed or a sidearm motion to giving it the spin required. The spin causes the ball’s angular momentum points in the direction of its long axis. At same time due to air drag‚ torque is pointing perpendicular to the angular momentum. The ball travels on a semi-parabolic curve and wind torque produces a small change in the ball’s angular momentum. This allows the ball to continue to turn around its trajectory. Therefore

Homework Introduction to Aerodynamics Name: Natalie Hume 1. In your opinion what has been the most important development/invention in the history of aerodynamics and why? I feel that I could pick something very complex and technical for this question. But I think in terms of science and simplicity I pick Bernoulli’s principle. This principle laid the foundation for the development of aerodynamics. It allowed for people to understand the relationship between pressure and velocity and continue

Controlled Assessment – Helicopters You need to research information (using the internet) that includes answers for the following questions: 1. How the turning rotor makes a helicopter move upwards 2. How the rotor is made to turn in a helicopter and in an autogyro 3. How autorotation is used to help land a helicopter safely if the engine fails 4. Why a helicopter; falling during autorotation‚ could reach a terminal speed without the pilot changing any controls 5. The effect of the weight of

that he would love to give Drag a surprise birthday party. Outside the sun was shining and he immediately knew what the surprise was going to be – a birthday barbecue! ‘I’d better go and find Croaky Crow and Sneaky Cat. I’ll need their help.’ And off he scampered. He got to the signpost and turned right. When he found Croaky Crow and Sneaky Cat he told them about his idea. They thought it was wonderful and immediately set about making a party list. “We mustn’t let Drag know‚” said Tiberius. “Now

Lab: Lift and Drag on an Airfoil Date Experiment Performed: 03/29/2012 Date Report Submitted: 04/12/2012 Names of Group Members: Grader ’s Comments: Michael Stevens Grade: Abstract: The Aerodynamics Lab: Lift and Drag on an Airfoil experiment examined the lift and drag on a NACA 0012 airfoil inside a wind tunnel. The objective of the experiment was to obtain information relating to the lift and drag of the airfoil‚ such as lift forces‚ lift coefficients‚ drag forces including

debating why drag racing is better than circle track "dirt track" racing. Here are my reasons why drag racing is better than circle track. Because you go way faster in a lot shorter distance and go in a straight line. In stock car racing you just go in circles. Drag racing is also better because when you are turning the corners in stock cars you run into people and your car gets all banged up. Then with getting your car banged up you have to put a new body on every couple of weeks. But in drag racing

was Mary Queen of Scots to Elizabeth’s rule? All substantial threats to Elizabeth’s position as Queen were symptoms of the tension between Catholicism and Protestantism. The threats posed by Mary Queen of Scots‚ as well as those of the Spanish Armada of 1588 and the war with Spain (which dominated the last twenty years of Elizabeth’s reign)‚ were consequences of a Catholic desire to gain supremacy in England. However‚ the extent to which the Catholic threat was centred on Mary Queen of Scots is

The individual sport I chose was badminton. For badminton there are a variety of tactics you can use to help win a game. Players should use different types of serves to vary their skills throughout the game and to ensure that their opponent will not predict which serves they are next going to perform. You can use an overhead clear to push the opponent to the back of the badminton court; it gives an opportunity to return an offensive shot. Angling the shuttlecock away from the player makes it harder

Elevation Not Having Air Resistance Not having air resistance as a factor in the practical has a big impact on the outcomes that you get‚ as there is nothing acting against gravity hence a greater acceleration the object has. Having Air Resistance However having air resistance also changes the outcome

HARDWARE 3.1 INTRODUCTION Quadcopter is a flying vehicle with six degrees of freedom which uses four rotors to push air downwards and to create a thrust force for keeping the quadcopter on the air. The pilot or flight control unit will control the orientation and tile of the multicopter by reading the data from the sensors. Gyro‚ accelerometer‚ magnetometer or GPS can be used to sense the tile‚ orientation and position of the vehicle. It can be used in many applications merely by changing the sensors
