What are 3 ways friction can be increased?
How can we increase friction while driving on the road?
Methods of increasing friction
when a ground or surface become slippery after rain or water splashing it is made rough by spreading sand to increase the friction. To decrease friction: (i) Friction between two surfaces can be decreased by using lubricants. (ii) Friction between two surfaces can be reduced by polishing them.

Answer: By making the moving surfaces rough : Types of vehicles have designed with grooves on the surface to increase friction. A large friction provides a better grip to vehicles on the road and prevents them from skidding. So, Sand and gravels are spread on grounds to increase friction.
To increase friction, the surfaces in contact have to be made rough. The two surfaces in contact can also be pressed harder to increase force between them. Use of adhesive materials that stick surfaces , also increases friction between them.
The three methods of increasing friction are: 1.) By applying more force to the object, 2.) By increasing the mass of the object that is causing friction, and 3.) By creating a rougher point of contact.
