What is frictional force? Explain with the help of examples, why frictional force is said to be a contact force.
Answers
Answer:
The force of friction is always exerted in a direction that opposes movement (for kinetic friction) or potential movement (for static friction) between the two surfaces. For example, a curling stone sliding along the ice experiences a kinetic force slowing it down.

Answer:
Frictional force refers to the force generated by two surfaces that contacts and slide against each other. ... If an object is pushed against the surface, then the frictional force will be increased and becomes more than the weight of the object.
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.
