Question

What is the cause of friction

Answer 1

Cause of friction.friction is a force that resists the relative motion between two objects or materials. the cause 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."

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.
• Deformations.

Intermolecular forces are responsible for friction. Roughness of the surface also contributes for friction.
