物体在竖直圆轨道内做圆周运动,何种情况最容易使轨道跳起.一般教辅资料都是以最高点作为临界点进行求解,且该解法得到广大师生的认可.但一般资料的处理是错误的.本文通过分析,找到轨道最容易跳起的位置,有的在圆周运动的最高点,有的不在圆周运动的最高点.错解的原因,在于混淆了物体做圆周运动的条件与轨道跳起的条件.
Objects in the vertical circular orbit circular motion, the situation is most likely to make the track jump .In general teaching materials are based on the highest point as the critical point to solve, and the solution has been recognized by the majority of teachers and students.But the general information Processing is wrong.This paper analyzes the location to find the most likely to jump orbit, some at the highest point of circular motion, some not at the highest point of circular motion. The reason for the misinterpretation is confusing objects to do circular motion conditions Conditions that jump with the track.
