when i rotate a screw at low speed he stop after sec.
but when giving him high initial speed he rotate,stop,and rotate backwards and stop again.
i think its because the drag force which got 2 components,1 take care of low speed velocities and the other high speed.
i'm not fully understand that,and i hope someone can answer me.
*sry for my bad english,lol
