Detailed explanation-1: -b) The frictional force is said to be a contact force because frictional force occurs when two surfaces come in touch with each other. Example of frictional force is walking on the road. For frictional force to act, there should be a contact between the foot and the road. Therefore, it is known as a contact force.

Detailed explanation-2: -A contact force is a force that acts between the point of contact between two objects. Pushing a car up a hill and kicking a ball are examples of contact force.

Detailed explanation-3: -Contact forces are those types of forces which result when the two interacting objects are perceived to be physically contacting each other. Examples of contact forces include frictional forces, tensional forces, normal forces, air resistance forces, and applied forces.

Detailed explanation-4: -Reaction force. An object at rest on a surface experiences reaction force . Tension. An object that is being stretched experiences a tension force. Friction. Two objects sliding past each other experience friction forces. Air resistance. An object moving through the air experiences air resistance .
