use lubricants like grease and oil...
Okay 2 ways for the friction to increase is speed and non lubricant
Three ways to decrease the force of friction are- 1.)Polishing 2.)Lubrication 3.)Ball Bearings
slows car and wears metal out
Friction is necessary for wheels to rotate and nails to keep in walls.
Without friction, we couldn't walk or grip onto anything.
Speed it up!
by giving it better aerodynamics you can reduce friction. but also the faster it goes the more friction it gets.
The four ways to decrease friction are: lubrication (using substances like oil or grease to reduce friction), using smoother surfaces, reducing the weight pressing the surfaces together, and using ball bearings or rollers to replace sliding friction with rolling friction.
In many ways
friction is caused by the irregularities in surfaces.less the irregularites, more the smoothness.so therefore to increase friction the best way is to make the surface rough.by doing so there will be a resistance against te direction of force.
There are three types of friction, static friction, rolling friction, and sliding friction. Static friction is friction between two surfaces that aren't moving relatively to each other. Rolling friction is friction between a rolling object and the surface that it is rolling on. Sliding friction is friction where an object slides, or rubs against, another surface.
