Rougher surface and more weight to the object increases friction
Thank you
Lubrication, is one way.Two ways to reduce friction are :.Lose weight.Wet the surface
friction \
Polish the interacting surfaces or decrease the normal force acting on the moving object.
Rubbing two things together. Even if you're just sliding across a carpet, that's friction too.
1. Increase the normal reaction acting on the objects by pressing them together. 2. Increase the coarse nature of the surfaces so that the coefficient of friction is also increased.
There are basically two ways to increase friction between two surfaces, which are, make them rougher (increased co-efficient of friction) or press them together with greater pressure. In either case, you are increasing the interaction between irregularities on the surfaces. Completely smooth surfaces would, in theory, be frictionless.
A lubricant such as oil and ball bearings are just (2) methods of reducing friction.
1. By friction. 2. by magnetism
