传统探究平抛物体运动规律实验存在一些缺陷,需要作出相应改进,减少实验误差,提高实验的可操作性,使实验更有利于学生探究平抛物体运动的规律。 Traditionally, there are some flaws in the experiment of flat-paver movement, which need to be improved to reduce the experimental error and improve the operability of the experiment, which makes the experiment more conducive to students to explore the law of flat paraboloid movement.
