The force which always opposes the motion of one body over another body frictional force. It acts between the two surfaces which are in contact with each other. Since frictional force arises when the surface of two objects are in touch with each other ,therefore, frictional force is an example of contact force.

Friction - a contact force
Friction is a force that opposes motion between two surfaces that are in contact with each other. This force arises due to the irregularities present on the surface of the objects which come in contact with each other. The force of friction acts in the direction opposite to the direction of motion or the applied force.
Contact force
Contact force is a force that arises when two objects are in contact with each other. This force can either be a pushing force or a pulling force. In the case of friction, it is a force that arises due to the contact between two surfaces.
Examples of contact forces:
- Friction
- Tension
- Normal force
- Air resistance
- Applied force
Conclusion
Friction is a contact force because it arises due to the contact between two surfaces. This force opposes the motion between the surfaces and acts in the opposite direction to the applied force.
