The causes of the resistive force of friction are
1.molecular adhesion
2.surface roughness
3.the plowing effect.
Adhesion is the molecular force resulting when two materials are brought into close contact with each other. Trying to slide objects against each other requires breaking these adhesive bonds. For years, scientists thought that friction was caused by surface roughness, but recent studies have shown that it is actually a result of adhesive forces between the materials.
But surface roughness is a factor when the materials are rough enough to cause serious abrasion. This is called the sandpaper effect.
When one or more of the materials is relatively soft, much of the resistance to movement is caused by deformations of the objects or by a plowing effect.

Friction is caused by the interaction between two surfaces as they rub against each other. Microscopic imperfections on the surfaces can catch on each other, resisting motion and causing heat to be generated. The amount of friction depends on factors such as the roughness of the surfaces and the force pressing them together.

What can friction cause?
Friction can cause wear and tear on surfaces, generate heat, decrease efficiency in mechanical systems, and create resistance to movement.
Does action and reaction cause friction?
Action and reaction do not directly cause friction. Friction is a force that opposes motion and is a result of the interaction between two surfaces in contact. While action and reaction forces may contribute to generating frictional forces, they are not the primary cause of friction.
How does friction cause a problem?
Friction can cause problems by creating resistance between two surfaces in contact, leading to wear and tear, heat generation, and energy loss. Excessive friction can also impede motion, reduce efficiency, and cause components to degrade prematurely.
How does friction not help us?
Friction can cause wear and tear on surfaces, decrease efficiency in machines, and produce heat that can be waste energy. In some cases, friction can also hinder motion or cause things to stick or get stuck.
Do two objects have to touch to cause friction?
No, two objects do not have to touch to cause friction. Friction can occur between surfaces even when there is a small gap or distance between them due to the attractive forces acting at a microscopic level.
What can friction cause?
Friction can cause wear and tear on surfaces, generate heat, decrease efficiency in mechanical systems, and create resistance to movement.
How does friction affect your skin?
Friction of the skin can cause chaffing and chapping. The friction can cause bed sores in people that are bedridden, and irritation in people that are active.
Does friction decrease or increase?
Wax, due to it filling the pores that cause friction will reduce friction.
Does inertia cause friction?
No.
What unbalanced force cause a ball to stop rolling?
Friction
Does action and reaction cause friction?
Action and reaction do not directly cause friction. Friction is a force that opposes motion and is a result of the interaction between two surfaces in contact. While action and reaction forces may contribute to generating frictional forces, they are not the primary cause of friction.
How does running cause friction?
when we run we push the ground backward it causes friction
Friction can cause a force that pulls on it how?
Friction is always against the direction of the movement.
Why is friction important in baseball?
friction is importent cause without it you can play baseball
How does friction cause problems for car users?
Friction causes wear and tear.
What does friction cause an increase in?
heat.
What does friction cause in the engine?
Heat.
