Surface area and downward force (most of the time gravity)
The force of friction is determined by the coefficient of friction (a value of "stickiness" given due to the roughness of an object's surface, the surface area and shape of the interface between the objects, etc) and the normal force (N) which is the opposing force (of the object's weight, for example) and is tangental to the frictional force.
How hard the surfaces push together and the types of surfaces involved
If your looking for the two main things then they are
1) What materials are in contact
2)How much are the surfaces are pressed together
Surface area and downward force (most of the time gravity)
The coefficient of friction between the two objects, and the weight/reaction force of the moving object.
Two main factors on which the force of friction depends are Mass of the object and nature of the object
roughness of surface explain.... please..
The 2 factors on which friction two body is depended uponThe mass of the body,the coefficient of Static or limiting or dynamic friction( as the case may be)Gravity too.
Friction is the main force that is responsible for the wear and tear of machinery, this is why mechanicalæparts are sometimesæoiled, to minimize the friction.
Pressure Gradient Force Coriolis Force Friction Force Pressure Gradient Force Coriolis Force Friction Force
Friction on a moving body is dependent on two basic factors and it can be represented as follows Friction force = (Coefficient of friction between the moving surfaces)*( Normal Force between the surfaces) Reducing any or both of the two factors reduce friction. Coefficient of friction can be reduced by: 1. Making the surfaces smoother.(effective for moving bodies in gas,liquid, or on solid/semisolid surfaces) 2. Applying 'Lubricant'. (effective for bodies moving on solid/semisolid surfaces) The normal force can be reduced for bodies in gas and liquids by reducing the press of the medium. (Hence vacuum and high altitude offer less friction than sea level for space crafts). Reduction of the normal force between solid bodies is not practical for machines since this will entirely alter their usefulness. But of course friction couplings, brakes etc use variation of normal force as main criteria for their operation.

The height of the bounce decreases because of many factors but two main factors are gravity and friction. * * * * * Gravity has nothing to do with the decrease in height. The two main factors are friction and the fact that the collision is not elastic.
Is it momentum friction electricity or gravity

The distance between and the mass of the two bodies are the main determining factors. Their masses and how far apart they are
There are three main formations of wind. These formations of wind include pressure gradient force, Coriolis force, as well as friction.
There are two main factors that affect personality. Genetics and environment.Of the two, environment is the major force.
the amount of friction depends on the type of surfaces that are rubbing against each other. when surfaces are smooth, they move against each other more easily. friction is greater between rough surfaces. in order to reduce friction in the moving parts of machines, scientists and engineers use oil and other lubricants. these lubricants make the surface smoother.
