If thrust is greater than drag, the plane will accelerate (speed up). If lift is greater than weight, the plane will rise. Opposed to thrust is drag, which comes from air resistance. Thrust is caused by the action of the plane’s propellers moving the plane forward. Lift is opposed by weight, or the force of gravity that is constantly pulling downward on the airplane. Lift is caused by differences in pressure when air flows over and under an airplane’s wings. Picture an airplane as you read about how these forces work together during flight. There are four main forces involved in flight: lift, weight, thrust, and drag. Try building a different style of kite and compare how it flies with how the sled kite flies. Build a similar kite but make it larger.Ħ. Build a new kite using the pattern described above but with a different material: For example, use newspaper and plastic straws instead of a paper bag and wooden skewers.ĥ. Make tails from different materials such as strips of plastic, paper, or fabric.Ĥ. Fly the same kite with one, two, three, or even more tails, and compare the difference each time.ģ. Once you master flying your kite, experiment with different tails and materials and their effects on the kite. Just enjoy watching it and be prepared for it to make its way down if the wind changes or stops. Once your kite is up and flying, there isn’t much you need to do.Staying away from trees is a good idea, too. As soon as the string becomes tight, slowly let out more and watch your kite rise higher in the air! When you feel the wind pushing against your kite, let it go, pushing it up into the air. Hold your kite in one hand and the spool of string in the other, then begin to run into the wind.You don’t need strong wind, but you do need constant wind. The best way to get a kite flying is to have a steady wind. Once the glue has dried, your kite is ready to fly! Up, Up & Away: Tips & Tricks Reinforce with a strip of tape so the tails won’t fly off in a gust of wind. Cut two tails each at least 2′ long and glue them to the kite – one next to each folded flap.
