how do kite sports work?

Like wallablack says... Whilst going in the same direction as the wind you go in a straight line....but when you go into the wind you move in a large zig zag motion side to side edging forward in small increments using the tension between the board and the wind to propel you.

Okay I will prove it.\n   there are 2 extreme cases of kite:\n  (i)when both sides become equal:\n      then it becomes a rhombus and area is .5*d1*d2\n  (ii) when one side is zero :\n      then it becomes a triangle and its area 1/2*b*h\nsatisfies the formula for kite (try drawing it)\n   Now the variation of area with the diff of sides is a smooth function must have a formula that satisfies both extremes. 1/2d1d2 satisfies the condition.\n   Assume that there is one more function satisfying the given criteria.It must have same value at all pts since area  \nis a unique entity.2 functions have the same graph and hence they must be identical.This proves that no other answer exists.

So you want to fly a kite? I do not blame you, as it could be fun.\n1. Tie two pieces of wood (you can use plastic tubing or bamboo) forming a cross. The ‘vertical’ piece can be 24 to 36” and the ’horizontal’ 14 to 20” long.\n2. Sail material:\na. If you use paper for the skin then tie string (a upholstery thread will do just fine) at the corners of the formed diamond or tips of the cross. Attach paper to the string. The string will prevent the paper from ripping. \nb. If you use fabric then there is hardly any need for the string, however hemming the edges is recommended. \n3. Attach 4 strings (use butcher cord or a  Polyester 40 lb line) each about 36” to the corners of the diamond then tie the loose ends together.\n4. Attach a tail made of ribbons (anything you fancy, be creative)\n5. Attach a line (butcher cord or  Polyester 40  lb line) to the ends you tied earlier and go fly that kite.\n6. I recommend a proper spool for your line.\n\nEnjoy.

There are two ways.\n\n1. This is the most likely way.  On a day with no wind, throw the ball straight up.  This is quite unlikely and requires a lot of skills.\n\n2. This one is impossible.  Throw the ball so hard that it goes around the Earth once before coming down.  Humans just don't have the power to do this.

Yes, if that is the direction they are flying. If the wind changes direction though they don't change. So not ALL the time as the question implies.

It's the "ball" in a game of badmitton that you swat over the net.  It's a weighted rubber half-ball with plastic "feathers" stuck in it allowing it to float more gently to the ground.

When a boomerang is correctly thrown, it is given spin at the moment it is released from the throwers hand. Spinning the boomerang causes air to rapidly flow over the airfoils creating lift that makes the boomerang fly. Because the boomerang is moving forward through the air, in addition to spinning, the arm rotating into the direction of flight creates more lift than the arm rotating away from the direction of flight. This causes asymmetrical lift or in other words more lift on one side of the spinning boomerang than the other

the ollie is the trick in skateboarding that brought the skateboard comunity to what it is today. it is when the board hops in the air by the grip tape and the shoes that are made for skatebarding it makes the board level out in the air. there is really nothing of physics in the trick. its just the grip tape on top of the board sticks to the specially designed shoes for skateboardng. like if you skate with tennis shoes it wouldn really stick to the board

If you use a fishing pole and line, the kite goes up with little effort or running and you can guide it through any obstacles, too.

Very simply, blowing wind spins the blades on a wind turbine -- just like a large toy pinwheel. The spinning blades turn a generator that makes electricity. \nwind Mills use blades to collect the wind’s kinetic energy. Windmills work because they slow down the speed of the wind. The wind flows over the airfoil shaped blades causing lift, like the effect on airplane wings, causing them to turn. The blades are connected to a drive shaft that turns an electric generator to produce electricity. \n\n\n"Basically, a wheel turns and it has a set of gears inside of it," he describes. "It has a stroke mechanism and the motor that goes up and down. There is a rod attached down to the top of the well and you have pipe and another sucker rod that goes all the way down to a solder down in the water in the well." \n\n\nThe biggest benefit of windmills is that they use a free source of energy to make more energy. As the wind blows, it turns the blades on the windmill, forcing the gears down below to react. Depending on what the windmill's specific purpose is, a windy day can provide a significant amount of energy for free. \n\n\n"Windmills get their power from the wind," Russ says. "The wind basically just turns a wheel. It has a couple of check valves and a few cup leathers down there so that it just lifts the water."

Kiteboards vary from surfboard style to small wake style.\n\nThey may seem like wakeboards but are designed to be used differently to cope with riding waves and holding an edge whilst being pulled in all directions.\n\nIt is possible to use a wakeboard to kitesurf if you ride on a really flat lake. Otherwise staying upwind becomes very difficult. Fins help this.\n\nThe most obvious difference is the use of full bindings on a wakeboard. Kiteboards usually have soft bindings which allow foot out maneuvers and bailing when necessary.\n\nFind your local kiteshop and check out some boards...they'll be happy to show you what you'll need as they come in many styles and sizes for different riders and riding styles.

Lizz –\nMost kites are designed for a specific range of wind velocities.  If your kite doesn’t list a range, then it usual default is 5 to 15 mph, especially for diamond shaped (the kind with a tail) or delta wing types.  Box kites need more wind.\nOnly the lightest kites and best flyers can usually get a kite up in a 2 mph wind.  I have flown kites in ranges from 2 to perhaps 35 mph.\nFor 5 mph (steady, with gusts up to 10 mph) most novices can get one up and keep it flying.\n7 mph is usually very easy, 10 isn’t bad.\nSimple kites have a single location to fix the kite string to the kite.  Better kites have ways of adjusting the “bridle” which changes the “tilt” of the kite toward the wind.  This allows them to be flown in a wider range of wind speeds.\nAll of the speeds mentioned above are “ground speeds,” that is the velocity of the wind at ground level.  Keep in mind that the weather report wind speeds are usually not recorded at ground level, so take them as a rough guide.  Also be aware that depending upon where you fly the kite, the difference in velocity only 100 feet up can make a real difference.  Some kites might be hard to get off the ground, but then soar like crazy once they get up.  You will need to experiment.

Badminton is a racket (or racquet) sport played by either two opposing players (singles) or two opposing pairs (doubles).\n\nPlayers at opposite ends of the court aim to hit a shuttlecock, more informally called a shuttle, over the net so that it lands inside the marked boundaries of the court, and aim to prevent their opponents from doing the same. Unlike a tennis ball, the shuttlecock flies with a lot of drag, and will not bounce significantly. The shuttlecock is always volleyed, and a rally ends as soon as it touches the ground. Badminton racquets have long shafts, to make it easier to impart a great deal of momentum to overcome the drag. The racquets are also much lighter than tennis racquets, because the shuttlecock is light. Badminton is one of the fastest sports in the world with shuttles reaching speeds of up to 332 km/h (206 mph), faster than the speed of the Eurostar train. Fu Haifeng of China set the official record July 3, 2005.\n\nMore info:\n\nhttp://en.wikipedia.org/wiki/Badminton
