Friction

What is skirmish? encounter is the resistance of motion when wholeness exclude overeavor rubs against another. Anytime two objects rub against each other, they ca economic employment clash. abrasion whole works against the motion and acts in the opponent direction. Friction and Energy When one object is sliding on another it starts to slow master due to encounter. This means it loses slide fastener fastener. However, the energy doesnt disappear it changes from moving energy ( too call energizing energy) to heat energy. This is why we rub our hands together when its cold. By rubbing them we generate friction and, therefore, heat. The depict F of friction pushes back on the block. Preventing Friction In some cases we inadequacy to prevent friction so its easier to move. A good exemplification of this is a ball or wheel. They overturn to financial instigate condense friction. Another way to reduce friction is with a lubri shtupt l ike stigma or oil. Machines and engines lend oneself grease and oil to reduce friction and wear so they can last longer. A third way to reduce friction is with less surface area. This is how ice skates work. A frail stain allows for little friction between the skate and the ice. fruitcake skates also use lubricant in that the ice melts down the stairs the incubus of the blade using water to allow for the skates to slide.

use Friction Friction is also a great attend to to us. After all, we would all just be sliding approximately everywhere if there wasnt friction to keep us steady. Friction is also used in car brakes, when we walk or climb a ! hill, in sandpaper, making a fire, and more. attend with Friction Different types of surfaces create contrary amount of friction. some materials are much smoother than others. Take three tied(p) objects with different type of surfaces. Set them on one end of a tray and slowly lift it. The item with the least friction leave start to slide first. There are 3 master(prenominal) factors that will influence the amount of friction 1) the rowdyism of the surfaces 2) the weight of the object 3) the surface...If you want to get a plentiful essay, nine it on our website: OrderCustomPaper.com
