Our topic is on encounter and what it is. So what is abrasion? friction is the ââ¬Å"evilââ¬Â of on the whole motion. No matter which direction an headway perishs in, crash will pull it the some other way. course something right, friction pulls it left. Move something up, friction pulls it down. encounter depends partly on the suavity of the contacting surfaces, a greater twitch 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, theyââ¬â¢re genuinely shingly and jagged. However, friction decreases with smoothness only to a definite degree. detrition actually increases between two extremely smooth surfaces be former of increased attractive electrostatic forces between their atoms. corrasion does not depend on the amount of surface field of battle that are in contact between the moving bodies or on the relative s peed of the bodies. What it does depend on though, is the order of the forces prop the two bodies together. When a body is moving over a horizontal surface, it presses down against the surface with a force advert to its burden. An increase in the weight of the body creates more resistance, so there is more friction. Friction is not all bad. It has a distribute do with life as we fare it on Earth.
Without friction, we wouldnââ¬â¢t be able to do a lot of the things that we contain to do. So why do we need friction? Itââ¬â¢s friction that enables us to walk, among other things. Friction is what keeps one foot planted on the gro und as the other one steps forward. Otherwis! e, without friction, the shift in weight would ca pulmonary tuberculosis 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 renewal of the wheel to slow down to a stop. There are two types of friction, ââ¬Å"static frictionââ¬Â and ââ¬Å"kinetic frictionââ¬Â. Static...If you precedent to get a full essay, order it on our website: BestEssayCheap.com
