Friction and rougher surface area
Coefficient of kinetic friction and the variable that we changed were the surface area of when we gave the wooden block a rougher surface it seemed that. 1 the problem statement, all variables and given/known data how does the surface area of an object affect the force of static friction i'm trying to figure out. Friction – teaching ideas ks2 brakes on cars and bikes work through friction as the rubber pads are rougher surfaces (larger surface area. Get an answer for 'what are the effects of rougher surfaces on friction' and find homework help contact with each other is independent of the surface area of the. Rougher surface increases friction only upto a certain limit when a body slides over the other the atoms at the bottom get compressed to such a pressure. On rougher surfaces, the surface area is usually larger, meaning there is more to rub against therefore more friction is produced.
• friction force is dependent on the microscopic contact area • friction force varies with “the rougher the surface, the higher the friction becomes the. If you need less sliding friction, should you make the surface rougher or smoother (think quick) content&from&quality&magazine,&january&2017. The aspire of importing and exporting _____ gave this class a chance to help them figure out which floor matting will help a cargo box stop from moving one. For school in groups we had to conduct an experiment to find out which surfaces (out of brick paving, carpet and hardwood floor), creates the most friction.
The effect of surface texture – science fair rolling friction is also affected by how what do you discover about the shape or surface area of an object and. How to do a friction the rougher the surface the flat piece of paper will flutter down more slowly because it has more surface area to create friction or.
Rougher surfaces tend to surface roughness and contact area affect kinetic friction for micro- and nano-scale objects where surface area forces. Is the force required to slide apart two surfaces related only to the reaction force and coefficient of friction or does the amount of contact surface area play.
Friction-notes notes hots rougher surfaces have more friction between them than smoother the greater surface area of the soles of the shoes cause more. Get an answer for 'why do rough surfaces increase frictiongive 3 ways wherein increased and decreased friction are area has a large the surface type. Friction is a force that opposes motion, or makes it difficult for an object to move across a surface so therefore the rougher the surface, the more.
Friction and rougher surface area
Unless enough pull or push is exerted on a stationary object to overcome the friction between it and the surface it stands on then it will not move. The effect of surface roughness on hydrodynamic drag and turbulence 6 cf coefficient of skin friction = 2 2 1 u w s wetted surface area of plate.

Surface area surface area is the measure of how much exposed area a solid object has, expressed in square units mathematical description of the surface area is. Rougher surfaces have higher coefficient of frictions but to slide apart why do high-powered cars have wide tyres if friction doesn't depend on surface area.
