Increases friction
Friction slows or stops motion when objects rub together.
The force when two materials rub together is called friction. Friction is a resistive force that opposes the relative motion or tendency of motion between two surfaces in contact. The magnitude of the frictional force depends on factors such as the nature of the surfaces and the force pressing them together.
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.
No, friction is a force. Gravity is the force that pulls matter to the centre of the earth. Friction is the heat between two objects pressed and rubbed together
of course,it's friction.

The normal force between the two objects and the coefficient of friction. Force of friction = normal force x coefficient of friction.
Friction is the force that opposes the relative motion of two objects. When two non-moving objects come into contact the friction between them can have a variety of effects on the objects. For example friction can cause the objects to stick together wear down the surfaces of the objects generate heat and dampen vibrations. Friction can cause two non-moving objects to stick together which can prevent them from moving at all. Friction can also cause the surfaces of the objects to wear down which can change the shape and size of the objects. Friction can generate heat which can cause the objects to become damaged or even destroyed. Friction can also dampen vibrations which can reduce the amount of noise from the objects.Overall friction is a powerful force that can have a significant effect on non-moving objects.
The coefficient of friction is a scalar value with no dimension. It is simply a ratio of the force of friction between two objects, to the force pressing those objects together (often the normal force). Slippery surfaces have lower coefficient of friction than rough surfaces.
No. Objects have to be in contact for there to be friction between them.
