Abstract: The motion of a particle on a non-smooth rotating disk is studied. According to the force equilibrium condition and the Newton's law,the problem of the static condition,the trajectory and the law of motion of the particle are solved by means of numerical solution,qualitative and quantitative analysis in rotating reference system.
