实验室中现有的离心轨道利用率太低,作用不大,它仅在讲完圆周运动和机械能之后,分析一个习题作演示之用。若进行改装组合,即可成为高中物理力学部分教学中常用的仪器,且改装简单,操作方便,形象直观。改装:如附图所示,将圆轨道在A、D、C、E、F、H处锯截,G为轨道最低点,AOE为水平直径,截去GH不用,斜轨与圆轨在G点吻接,圆轨与斜轨在同一竖直平面内,在A、C、D、E、F处的轨道外侧各焊接插销一个(插孔用2厘米长金属管,插头用粗细适中的铁丝即可)。圆轨后面加一木板,增加圆轨强度,固定AH,增
The existing utilization rate of the centrifugal orbit in the laboratory is too low to have a significant effect. It only analyzes an exercise for demonstration after the completion of circular motion and mechanical energy. If the combination is modified, it can become a commonly used instrument in the teaching of physics and mechanics in high school, and the conversion is simple, the operation is convenient, and the image is intuitive. Modification: As shown in the attached drawings, the circular orbit is sawed at A, D, C, E, F, and H. G is the lowest point of the orbit, AOE is the horizontal diameter, and GH is not used. Ramp and round orbit are at G Point the kiss, the round rail and the ramp in the same vertical plane, in the A, C, D, E, F at the outer side of the track a welding pin (jack 2 cm long metal pipe, plug with a moderate thickness wire Can). Add a board behind the round rail to increase the round rail strength, fix AH, increase
