Question

What is the caise of friction??

Answer 1

Friction is a force that resists te relative motions between two objects ur more materials.

CAUSES OF FRICTION:-

Adhension is a molecular force resulting when two objects are brought into close to each other trying to slide objects against each other requires breaking this adhensive bonds.

surface roughnes is also... a factor

Answer 2

Explanation:

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.
