Abstract

A glider is a kind of fixed-wing aircraft that does not use any power. After takeoff, it relies on the reaction force of the air acting on its lifting surfaces for free flight. So, an experiment is designed to research some information and the relationship between gliders. The method of controlling variables is used to study the theme and compare the data from different experiments to get a result. The experimental results are consistent with the actual law. For example, although the process of making the paper glider has some problems, the behavior of the glider would not be observed, so that the gravity point may have a large difference that influences the flight. In this case, there are no checks and changes on the glider in the experiment. This is a mistake of people who do this experiment, which causes the result to become different. The theories are summaries of natural phenomena and laws. These theories need to be proved, and the experiment can verify their correctness, so experimenting is essential and meaningful. In addition, new phenomena may be found in the new study, which can lead the next and further research. In this process, it may promote the development of new technologies and skills and improve creativity.
