自制的“动态力的分解演示仪”可以非常直观地演示在有滑轮情况下的力的动态变化,能将学生难以理解的力的变化借助弹簧测力计直观地反映出来。该演示仪还可以直接应用于力的分解的教学。
Homemade “Demonstration of dynamic force ” can be very intuitive to demonstrate the dynamic change of the force in the case of a pulley, the changes can be difficult to understand students with the force of the spring dynamometer intuitively reflected. The demo instrument can also be applied directly to the teaching of force decomposition.
