高中物理第三册(选修)第73页,小实验“研究向心力的大小跟什么因素有关”中说;“尼龙绳的拉力是使橡皮塞做圆周运动的向心力,这个向心力的大小可以从测力计上读出.”并且给出实验装置图如图1.
High School Physics Book 3 (elective), p. 73, said in the small experiment “A study of the magnitude of the centripetal force is related to what factors”. “The tension of a nylon rope is the centripetal force that causes the rubber stopper to make a circular motion. The centripetal force can be measured from the force. Read on the meter." And give the experimental device as shown in Figure 1.
