Name a method to _
A) Reduce friction
B) Increase friction
Method of decreasing and increasing friction
Method of decreasing friction:
By polishing
Ball-bearing
Lubricants
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.
