Without friction, we couldn't walk or grip onto anything.
Friction is necessary for wheels to rotate and nails to keep in walls.

There are different ways through which helpful friction be increased. The easiest way is using coarser or rougher surface to increase resistance.
Friction can be helpful and not helpful it is not helpful when you are running because it slows you down hope that'll help!!!! ;)
Friction lets the drive wheel push you forward, and allows your brakes some bite. Friction make it possible to hold on to the bars. Friction lets you steer.
Friction is helpful as it allows us to walk, hold objects, and write. It also helps stop vehicles and machines by providing traction. However, friction can be harmful as it causes wear and tear on moving parts, reduces speed in vehicles, and can cause injuries when there is too much resistance.
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 in providing grip or traction, allowing us to walk, drive, or even hold objects securely. It is also useful in slowing down or stopping objects in motion, preventing them from sliding or moving uncontrollably.
Friction is helpful between car tyres and roads for grip. It is also sometimes used for heating as friction generates heat.
By using kinetic friction
Friction is helpful in situations like when you are standing on a hillside. Static friction between your shoes and the surface are stopping you from slipping. Friction is not helpful in situations like when you are pulling something heavy. Some of the energy you are putting into pulling is going into heat from kinetic friction and making your job more difficult.
Helpful Friction.
