Answer:
Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact.
increase friction:
one is by making the surfaces rough and the other by increasing the mass of the object that is moving. For example, the tyres of vehicles have treads (these are the 'designs' that you can see on the tyre surface), which increase the friction between the tyre and the road.
decreasing friction:
The use of bearing surfaces that are themselves sacrificial, such as low shear materials, of which lead/copper journal bearings are an example. Replace sliding friction with rolling element friction, such as with the use of rolling element bearings.

Answer:
The force, which opposes the relative motion between two surfaces in contact is known as friction
The cause of friction--
The interlocking of irregularities of the two surfaces opposes the motion of one object over the other and give rise to force of friction. Friction is caused by the interlocking of irregularities in the surface of two objects which are in contact with each other.
