In the first section of the “Physics” section of the High School “Physics” (Test Revision, Compulsory), there is a demonstration experiment of an object doing curve motion conditions in the first section of the Curve Movement. This experiment is too sketchy in the teaching materials. Under normal circumstances, this experiment demonstrates The effect is not obvious, making teaching hard to be persuasive. The author explored and improved this demonstration experiment so that this experiment can achieve its purpose and the effect is quite good.
