【Abstract】 By solving the nonlinear dynamic differential equations in perfect elastic collision process between a ball and a bar rotating about a fixed axis,this paper deals with the transformation of the kinetic energy and the potential energy of compressive deformation in the collision process.It has been concluded that the sum of the kinetic energy of the ball and the rotational energy of the bar is strikingly unconservative.更多还原
