encounter is the resistance of motion when wholeness stop overeavor rubs against another. Anytime two objects rub against each other, they ca economic consumption clash. Friction whole works against the motion and acts in the opposite direction.
Friction and Energy
When one object is sliding on another it starts to slow master due to friction. This means it loses zip fastener. However, the energy doesnt disappear it changes from moving energy (also call kinetic 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 want to prevent friction so its easier to move. A good example of this is a ball or wheel. They overturn to financial aid condense friction. Another way to reduce friction is with a lubricant like grease or oil. Machines and engines use 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 blade allows for little friction between the skate and the ice. fruitcake skates also use lubricant in that the ice melts down the stairs the weight 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 virtually 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.
examine with Friction
Different types of surfaces create different amount of friction. many 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 will start to slide first. There are 3 main 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, order it on our website: Orderessay
