FRICTION

 

A collision/Friction is a force that resists the cohesive movements of solid surfaces, layers of liquid, and the properties of smooth objects. There are many types of conflicts:

* Dry friction is the force that opposes the lateral lateral movement of two solid areas in which it is touched. The dry collision is divided into a fixed collision ("butt") between immovable surfaces, and a kinetic collision between a moving surface. With the exception of atomic or molecular collisions, dry collisions often occur with a combination of earth elements, known as asperities (see Figure 1).

* Liquid friction refers to the friction that exists between layers of complementary fluids

* The softened coating is a matter of liquid collision where the lubricant fluid separates the two solid surfaces.

* Skin tension is part of the pull, a force that resists the movement of fluid on the surface of the body.

* Internal friction is the force that opposes the movement of elements that make up a solid object while undergoing transformation.

When a contact area moves in relation, a collision between the two areas converts kinetic energy into thermal energy (i.e., converts performance into heat). This material can have amazing results, as shown by the use of friction made by brushing pieces of wood together to make a fire. Kinetic energy is converted into thermal energy whenever a collision is moved, for example when a viscous fluid is activated. Another important consequence of many types of collisions can be wear, which can lead to reduced performance or damage to objects. Conflict is a scientific aspect of tribology.

Conflict is attractive and important in providing traction to facilitate movement around the world. Many cars in the world rely on collisions to speed up, slow down and change lanes. Sudden decrease in pulling can cause loss of control and accidents.

The outbreak is not in itself a fundamental force. Dry friction arises from a combination of inland adhesion, surface roughness, tension, and soil contamination. The complexity of this interaction makes counting conflicts from the original principles ineffective and requires the use of powerful methods of analysis and doctrinal construction.

Conflict is an unsavory force - work done in a conflict depends on the path. In the event of a collision, some kinetic energy is constantly converted into thermal energy, so electrical energy is not conserved.
