### friction

resistance to movement created when two surfaces are in contact. When friction is present, movement between the surfaces produces heat.

### friction

1. a state of conflict between persons
2. the resistance encountered when one body is moved in contact with another
3. effort expended in rubbing one object against another

### friction

(Learning Modules / Geography / Geography of energy) The resistance to motion when once surface moves against another.

### Friction

Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: When surfaces in contact move relative to each other, the friction between the two surfaces converts kinetic energy into heat. This property can have dramatic consequences, as i...

### friction

A resisting force between two surfaces that are sliding against each other. Static friction is the frictional force that opposes any attempt to start a body moving that is a rest. Kinetic friction is the frictional force that tends to slow a body already in motion. The force due to kinetic friction ...

### Friction

Friction is a force which tends to make moving objects slow down. Friction also prevents objects from slipping over one another - so for example, friction helps keep your backside on a seat and it allows people to stand upright without their feet slipping out from under them. Friction due to fluid flow is called drag

In meteorology, it is the turbulent resistance of the earth on the atmosphere. Considered as the resistance of fluids (air and water) to the relative motion of a solid body. The amount is dependent on the size and shape of the body.

### Friction

In physics, friction is the effect of rubbing, or the resistance which a moving body meets with from the surface on which it moves. Friction arises from the roughness of the surface of the body moved on and that of the moving body. No such thing can be found as perfect smoothness of surface in bodies. In every case there is, to a less or greater ex...

### friction

In physics, the force that opposes the movement of two bodies in contact as they move relative to each other. The coefficient of friction is the ratio of the force required to achieve this relative motion to the force pressing the two bodies together. Two materials with rough surfaces rubbing together will change kinetic energy into heat and sound ...
