中学物理教学大纲规定:要进行“研究物体在弹力和重力作用下的圆周运动”的实验教学。在此,提出它的实施方案。实验前学生要获得对本实验如下的描写。实验目的——通过实验检验作圆周运动的物体在力的作用下具有加速度,这个力是作用于它的两个力的合力。
The syllabus for secondary school physics stipulates that the experimental teaching of “research on the circular motion of objects under the action of elastic force and gravity” should be carried out. Here, its implementation plan is proposed. Before the experiment, the students obtained the following description of this experiment. The purpose of the experiment is to test that an object moving in a circular motion has an acceleration under the force of an experiment. This force is the resultant force of two forces acting on it.
