摘要: 详细讨论了当向心力突然增大后,原来作匀速圆周运动的小球其运动轨迹的变化情况,证明了小球将作螺线运动.

关键词: 向心力, 匀速圆周运动, 螺线运动

Abstract: A small ball is making circular motion at the uniform velocity, the centripetal force has suddenly increased,it is proved that the small ball will generally make a spiral motion.

Key words: centripetal force, circular motion at the uniform velocity, spiral motion
