Method of decreasing friction:
By polishing: Friction between two surfaces can be reduced by polishing them. The interlocking and projections are minimized by this method.
Ball-bearing: As the rolling friction less than the sliding friction consequently in rotating machinery, the shafts are fixed on the ball bearing so that the friction can be reduced considerably. For example-the free wheel of a cycle, the axle of a motorcar, the shafts of the motor dynmo etc. are provided with ball-bearing.
Streamline: The friction due to air is reduced by making the automobiles streamline.
Methods of increasing friction:
By making the surface rough friction can be increased. Examples of increasing friction-the tyres of a motor car and bicycles are made rough to increase the friction .when a ground or surface become slippery after rain or water splashing it is made rough by spreading sand to increase the friction.
