A. Flight Control. B. How does a kite fly? C. Choose the best location. D. Remember to always fly with the wind at your back. E. Ask how you know which way the wind is blowing. F. Kites don't fly well when there is too little or too much wind. G. Having someone to hel...
The surface above the kite develops a low pressure while the surface below the kite develops a high pressure, enabling it to sustain its flight. A kite's lift is also decided by its surface area. Greater the surface area, greater is the lift. So, whenever you see someone flying a kite...
look a lot smarter than all those other people who are running around! FLIGHT CONTROL Always keep an eye on your kite while it is flying. If something goes wrong, you want to see it and fix things before a crash. Don't be tempted to let out too much line. One or two hun...
Chuck a stone off the side of a mountain and it will plummet as well. Sure, steel ships can float and even very heavy airplanes can fly, but to achieve flight, you have to exploit the four basic aerodynamic forces: lift, weight, thrust and drag. You can think of them as four arms ...

【解析】根据文中信息"Try," said the big kite, "only try! Or I fear you never will learn at all.(试一下,大风筝说,就试一下,否则恐怕你永远不能学会)"可知大风筝是在鼓励小风筝,故选C。A他什么都没说;B他嘲笑它;D他帮助他飞。 3.【答案】A 【解析】根据文中内容可知小风筝最后飞上高空是因...
4. Decorate: Draw your favorite patterns on the kite or stick some decorations on it. 5. Tie the thread: Tie the thread to the head and tail of the kite to control its flight. 6. Test flight: Test the kite in an open area, adjust the length of the thread and the balance of the...
Cut out the fabric, ensuring it's slightly larger than the frame to allow for folding and attaching. Fold the fabric edges over the frame and secure them with thread or hot glue, making sure there are no loose ends that could tear off during flight. Step 5: Add the Tail A tail is ...
I had to fly in a straight line. If I veered to the right, I had to shift my weight to the left to get back on course. If I veered to the left, I had to shift my weight to the right. During the the entire flight, I was constantly adjusting my speed and position (beginners ...
Having covered the basic physics of flight and the ways in which an airplane uses them to fly, the next obvious step is to consider navigation. How does an airplane turn in the air? How does it rise to a higher altitude or dive back toward the ground?
