Friction occurs when two bodies slide over each other.Friction can be defined as the resistance to motion experienced when two surfaces in contact move with respect to each other.
Whenever two bodies slide over each other,each exerts a force which opposes movement.We can see that as it becomes harder to move the objects.Rough and coarse surfaces offer more friction than smooth and polished surfaces.We can walk easier on rougher surfaces than on smoother surfaces due to friction.Friction can also be produced by air and water which can oppose the motion of vehicles.
