centrifugal force
【释义】： ［物］离心力〔If you swing a ball on a string around your head，the centrifugal force of the ball’s weight will keep the string taut and the ball swinging．The centripetal force of your hand holding the string will keep the ball from flying away．如果你将一根绳子上的一只球绕著的头部旋转，球的重量的离心力会使绳子拉紧球体保持旋转。你的手握绳子的离心力会保持球不至于飞出去。〕 |
