Friction is the pull between two or more objects that causes the objects to slow and eventually come to rest. There are many types of friction, such as air friction or surface friction, but all types of friction create a pull on one another.
The primary causes of friction are surface roughness, the plowing effect and molecular adhesion. Surface roughness is when serious abrasion occurs due to the roughness of the materials in contact. The plowing effect involves deformations of the objects that cause resistance to movement when the materials are relatively soft. Adhesion refers to the molecular force that results from two materials brought into close contact with one another. To slide objects against each other, it is essential to break the adhesive bonds between them. According to recent scientific studies, friction occurs because of adhesive forces between materials. Ultra-smooth and sticky materials fall under the molecular adhesion category. There are varying degrees of surface roughness in solid materials. Even a smooth surface has small bumps that interfere with sliding motion. When the surfaces of two hard, solid materials are very rough, friction occurs due to the abrasion that happens when two objects slide against each other. Deformations are another cause of friction. Deformations form when soft materials deform under pressure and lead to an increase in resistance to motion. For example, when a person stands on a rug, he sinks in slightly, causing resistance as he drags his feet along the rug's surface. Resistive force is created, and friction occurs when the deformation becomes large.

Friction causes kinetic energy to be coverted into?
Friction causes kinetic energy to be converted into heat energy.
Friction causes mechanical energy to be transformed into what?
Friction causes mechanical energy to be transformed into heat energy.
What are the main causes of friction?
The main causes of friction are roughness of surfaces, the force pushing the surfaces together, and the type of materials involved. Friction occurs when these factors create resistance to the motion of an object across a surface.
When friction causes a object to stop energy is converted into?
When friction causes an object to stop, the kinetic energy of the object is converted into thermal energy due to the heat generated by the friction between the object and the surface it is sliding on.
What force causes a car to stop?
The force of friction between the tires and the road surface is what primarily causes a car to stop. When the brakes are applied, the brake pads press against the rotating wheels, generating friction that slows down the car.

How are friction notuseful?
Friction is not useful when ever we do not want it. Examples would be when two materials are rubbing against one another. The friction of ropes in pulleys eventually causes wear on both; friction of shoes or straps against the body causes blisters; friction airplanes travelling through the air - friction causes the plane to get hot; the moving parts of an engine get hot from friction...
What causes friction in satic electricity?
There is no friction IN static electricity. However static electricity can be caused BY friction.

Friction
How is friction defined scientifically?
Friction is a force present when things rub against eachother. Friction causes heat energy, and it also causes motion between surfaces to be reduced.
How does friction cause problems for car users?
Friction causes wear and tear.
How does running cause friction?
when we run we push the ground backward it causes friction
What is heat and what causes it?
Friction causes heat. Heat is a source of energy.
What causes static forces?
Friction is the force that causes static charge
