Friction is defined as the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several kinds of friction, which include dry friction, fluid friction, lubricated friction, skin friction, and internal friction. Dry friction resists relative lateral motion of two solid surfaces in contact. It is then divided into two different categories; static friction and kinetic friction. Static friction deals with non-moving surfaces, while kinetic friction deals with moving surfaces. Fluid friction describes the friction between layers within a viscous fluid that are moving relative to each other. Contrary to the belief of most people, fluid friction is the friction that is involved in driving a car, since the molecules in the air are technically a fluid. Lubricated friction is a type of fluid friction where a fluid separates two solid surfaces. Skin friction is one of the components of drag. Drag is the force resisting the motion of a solid body through a fluid. The last kind of friction is internal friction. This is the force resisting motion between the elements making up a solid material while it undergoes deformation. One very important element when it comes to friction is kinetic energy, which is the energy that an object possesses dude to its motion. Kinetic energy is converted into heat whenever two surfaces in contact move relative to each other. Heat is the energy transferred from one system to another via thermal interaction. Friction is not a fundamental force and it occurs because of the electromagnetic forces between charged particles, which constitute the surfaces in contact. Since these interactions are extremely
