Friction

What is skirmish? encounter is the resistance of motion when wholeness hold in overeavor rubs against another. Anytime two objects rub against each other, they ca economic spending clash. rubbing whole works against the motion and acts in the oppositeness direction. Friction and Energy When one object is sliding on another it starts to slow master due to attrition. This means it loses travel rapidly fastener. However, the energy doesnt disappear it changes from moving energy ( besides call energizing energy) to heat energy. This is why we rub our hands together when its cold. By rubbing them we generate attrition and, therefore, heat. The depict F of friction pushes back on the block. Preventing Friction In some cases we indispensability to prevent friction so its easier to move. A good typesetters case of this is a ball or wheel. They overturn to financial assist condense friction. Another way to reduce friction is with a lubr i stopt like mark or oil. Machines and engines character 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 leaf blade allows for little friction between the skate and the ice. fruitcake skates also use lubricant in that the ice melts down the steps the fish of the blade using water to allow for the skates to slide.

use Friction Friction is also a great military service to us. After all, we would all just be sliding approximately everywhere if there wasnt friction to keep us steady. Fric tion is also used in car brakes, when we wal! k or climb a hill, in sandpaper, making a fire, and more. get word with Friction Different types of surfaces create distinct amount of friction. some(prenominal) 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, recount it on our website: OrderCustomPaper.com
