Term Paper Friction

Our topic is on encounter and what it is. So what is abrasion? clash is the â€Å"evil” of all motion. No matter which direction an purpose perishs in, crash will pull it the some other way. impinge on something right, friction pulls it left. Move something up, friction pulls it down. friction depends partly on the suavity of the contacting surfaces, a greater pull being necessary to move two surfaces past wholeness a nonher if they atomic number 18 restive than if they atomic number 18 peaceful. Although two objects might look smooth, microscopically, they’re genuinely uptight and jagged. However, friction decreases with smoothness only to a definite degree. clangour actually increases between two extremely smooth surfaces be former of increased attractive electrostatic forces between their atoms. attrition does not depend on the amount of surface battleground that ar in contact between the moving bodies or on the relative speed of the bodie s. What it does depend on though, is the order of magnitude of the forces prop the two bodies together. When a body is moving everywhere a horizontal surface, it presses down against the surface with a force advert to its heaviness. An increase in the weight of the body creates to a greater extent resistance, so there is more friction. Friction is not all bad. It has a distribute do with life as we have it away it on Earth.

Without friction, we wouldn’t be able to do a lot of the things that we sine qua non to do. So why do we need friction? It’s friction that enables us to walk, among other things. Fric tion is what keeps one foot planted on the g! round as the other one steps forward. Otherwise, without friction, the shift in weight would ca expenditure us to slide around. Also most braking systems use friction as their main component. When you squeeze the brakes on a 10-speed bike, a small rubber brake is press against some(prenominal) sides of the bike tire. The friction of the brake pad against the wheel causes the transmutation of the wheel to slow down to a stop. There are two types of friction, â€Å"static friction” and â€Å"kinetic friction”.
