Question

what is friction, and what is the cause of friction​

Answer 1

Friction is the resistance that one surface or object encounters when moving over another.

The causes of the resistive force of friction are:

• Molecular Adhesion
• Surface Roughness
• Plowing effect

• Adhesion is a molecular force that arises when two materials are brought close to each other.

• Surface roughness is a factor in friction when the materials are rough enough to cause serious abrasion.

• When one or more of the materials are relatively soft, much of the resistance to movement is caused by deformations or a plowing effect.

Answer 2

❄ANSWER⛄

Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact.

The interlocking of irregularities of the two surfaces opposes the motion of one object over the other and give rise to force of friction. Friction is caused by the interlocking of irregularities in the surface of two objects which are in contact with each other.
