The motion of a sphere moving on a rough horizontal surface changes from pure sliding (without rolling) to pure rolling (without slipping). In this process, the force of friction (i) initially acts opposite to the direction of motion and late in the direction of motion (ii) cause linear retardation (iii) causes angular acceleration (iv) stops acting when pure rolling begins
