Question

what are the causes of friction
​

Answer 1

☘️ CAUSES OF FRICTION ☘️

Friction is the force that stood the moving object.

Roughness of the surfaces causes friction.

If the roughness is more on the surface friction will be more.

Smooth surfaces have very little friction.

It can also be caused by bumps on two touching surfaces.

Rubber has a lot of friction.

Answer 2

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
