Question

Give Any two cause of friction​

Answer 1

Answer:

Friction is a force that resists the relative motion between two objects or materials. The causes of this resistive force are molecular adhesion, surface roughness, and deformations. Adhesion is the molecular force resulting when two materials are brought into close contact with each other.

Answer 2

What is Friction:

Friction is a force that resists the relative motion between two objects or materials.

CAUSES OF FRICTION:-

• Molecular Adhesion:

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

• Surface Roughness:

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

• Plowing effect:

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