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

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

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

Year 11 Physic Controlled Assessment The factors that affect the motion of a falling object 1. Gravity 2. Mass 3. Weight 4. Aerodynamic/Streamline 5. Surface Area 6. Shape 7. 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

Discussion: As shown in the result section‚ the drag force increases steadily with increasing wind speed. However‚ for high wind speeds with largest sphere‚ this is not true. There is a region that the sphere experiences a large drop of drag force. The drag coefficient remains relatively constant for most cases. However‚ when a Reynolds number reach about 300‚000‚ and the sphere is the largest one; for this case‚ the drag coefficient drops abruptly. We also found that for the same wind speed‚ the

dimensional analysis is to define a suitably idealized representation of a phenomenon by listing the relevant variables‚ called the physical model. The second step is to learn the consequences of the physical model and the general principle that complete equations are independent of the choice of units. The calculation that follows yields a basis set of nondimensional variables. The final step is to interpret the nondimensional basis set in the light of observations or existing theory‚ and if necessary to modify

The Physics of Badminton Gerard Ramos Physics 4A Prof. Scott Hildreth I would like to start off with a light introduction to the sport of Badminton. Badminton is a sport that isn’t too popular in the United States; some people would even say that it shouldn’t even be called a “sport”. The majority see badminton from a “back-yard sport” point of view‚ part of this is due to the lack of actual badminton court facilities in America‚ also because it’s a bit expensive to play. Badminton is not

INTRODUCTION A key aspect in attempting to improve and perfect ones sporting skills is to understand the biomechanics that are involved. Biomechanics is the study of how the body moves and the efficiency of movements (INCLUDE TEXTBOOK REFRENCE). By understanding the principles underpinning an athlete’s performance using biomechanics‚ it enables you to detect errors easier in the technique and adjust the athletes’ performance accordingly. Good morning my name is Melyssa and today I will be analysing
