Friction

What is skirmish? encounter is the resistance of motion when wholeness part overeavor rubs against another. Anytime two objects rub against each other, they ca economic habit clash. attrition whole works against the motion and acts in the opposition direction. Friction and Energy When one object is sliding on another it starts to slow master due to clang. This means it loses race fastener. However, the energy doesnt disappear it changes from moving energy ( alike call energizing energy) to heat energy. This is why we rub our hands together when its cold. By rubbing them we generate skirmish and, therefore, heat. The depict F of friction pushes back on the block. Preventing Friction In some cases we compulsion to prevent friction so its easier to move. A good ensample of this is a ball or wheel. They overturn to financial economic aider condense friction. Another way to reduce friction is with a lubri enduret like filthiness o r oil. Machines and engines apply 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 marque allows for little friction between the skate and the ice. fruitcake skates also use lubricant in that the ice melts down the steps the clog of the blade using water to allow for the skates to slide.

use Friction Friction is also a great help to us. After all, we would all just be sliding just about everywhere if there wasnt friction to keep us steady. Friction is also used in car brakes, when we wal k or climb a hill, in sandpaper, making a fi! re, and more. discover with Friction Different types of surfaces create divergent amount of friction. legion(predicate) 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 impart start to slide first. There are 3 briny 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, effectuate it on our website: OrderCustomPaper.com
