Question

Explain why frictional force is said to be a contact force
​

Answer 1

Answer:

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

Answer 2

Answer:

Explanation:

Friction is a contact force when two surfaces interact. The second equation is the kinetic frictional force that is used when two surfaces are sliding against each other. 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.
