Definition:
Friction is defined as the resistance offered by the surfaces that are in contact when they move past each other.
Types of Friction:
There are four types of friction and they are classified as follows:
1) Static friction
2) Sliding friction
3) Rolling friction
4) Fluid friction
All four types of frictions are different from each other. For example, static friction is the friction that acts between the surfaces when they are at rest with respect to each other. In contrast, sliding friction is the resistance created between any two objects when sliding against each other.
