Helpful Friction.

Friction can be reduced by using lubricants like oil or grease on surfaces. To increase friction, surfaces can be roughened or materials with higher coefficients of friction can be used. Adjusting the weight or pressure between the surfaces can also increase friction.

Friction is helpful in preventing slipping while walking or driving on the road. The friction between the tires and the road surface allows for better traction, leading to improved control and stability.
There are different ways through which helpful friction be increased. The easiest way is using coarser or rougher surface to increase resistance.
Deep tread added to snow tires.
Friction can be helpful and not helpful it is not helpful when you are running because it slows you down hope that'll help!!!! ;)
Decreased friction is very helpful in working machinery, because friction causes wear and tear.Mainly its very helpful in moving parts. Decreased friction is also helpful in electric cables and wires, as reduced friction reduces energy loss via heat.
Friction is helpful between car tyres and roads for grip. It is also sometimes used for heating as friction generates heat.
One example is using sandpaper to increase friction between objects. Another example is applying anti-slip mats or tapes to surfaces to prevent sliding. Additionally, car tires are designed with treads to increase friction with the road for better traction.
One example of intentionally increasing friction is by roughening the surfaces that are in contact, such as adding sandpaper to the bottom of a shoe to increase grip. Another example is tightening the screws or bolts holding two surfaces together to create more friction between them.
