What Is Little In Friction?
In the context of friction, "little" would typically mean that there is not much resistance or opposition between two surfaces in contact. This would result in smoother movement and less energy loss due to friction.
How does a styrofoam relate to friction?
Styrofoam has a low coefficient of friction, meaning it is very smooth and produces little resistance when in contact with other surfaces. This low friction coefficient allows styrofoam to slide easily across surfaces.
Why does oiling and lubricating reduce friction?
no substance is perfectly smooth.it has tiny bumps and bruises and when two surfaces move over each other the bumps and holes in get in each other's way.oil covers up these bumps.it also forms a layer between the two surfaces and prevents direct contact between them.there is very little direct contact between the holes and this way the friction is reduced
Why there is no friction on space?
Friction is the force that resists motion between two surfaces in contact. In the vacuum of space, there are no surfaces or molecules to create this friction. Objects in space can move freely without friction because there is very little resistance to their motion.
Does height affect friction?
Actually the study of friction is complicated and the usual statement that, say, the kinetic frictional force is proportional to the weight of the object is more a rule of thumb than a law of physics. For one thing, friction depends on the exact nature of the surfaces in contact, what materials the surfaces are made of, what is the microscopic texture of the materials, etc. If you are considering two solid surfaces, one way of thinking about the friction between them is that on the microscopic level, the surfaces are actually very rough, with many sharp peaks and valleys. When you put two materials together with little force between them, they really only touch at the tips. So if you were to pull sideways, it would take little force to move the materials across each other. But if the force between the blocks increases, then the tips penetrate into the valleys, they bend to allow a larger area of surface to come into contact, they even can make microscopic welds between the materials. In this case, it takes a much bigger sideways force to slide the materials across each other. Hence, the increase in friction.

What has little and what has lots of friction?
Ice has little friction. Sandpaper has lots of friction.

Is heat little friction or is it great friction?
heat is really half of friction

Is friction a contact or non contact force?
friction is a contact force
What are the most difficult surface to maintain any type of friction?
The most difficult surfaces to maintain friction on are typically those that are very smooth, non-porous, and have low coefficient of friction materials like ice or glass. These surfaces offer little to no resistance to objects moving across them, making it challenging to generate or maintain friction.
Latest trends to reduce friction?
One is magnetic bearings where there is little or no contact from the rotating shaft. Also magnetic levitation, as used in high speed trains.
Where on a bicycle is friction not important?
In the bearings, where you want as little friction as possible.
What are somethings with little friction?
Ice and marble floor have little friction and results in objects slidding as they go across the surface.
