Copyright © Restrictions Uses of Friction by Ron Kurtus (revised 21 May 2009) Although you normally
hear about trying to reduce or eliminate friction, it actually has some important uses. Since friction is a resistance force that slows down or prevents motion, it is necessary in many applications to prevent slipping or sliding. In those cases, there is an advantage of having friction. However, too much friction can be a nuisance, because it can hinder motion and cause the need for expending extra energy. A good compromise is necessary to get just enough friction. Questions you may have include: What are important uses of friction? How is friction a nuisance? What is a good compromise for using friction? This lesson will answer those questions. Useful tool: Metric-English Conversion Important uses In some situations, friction is very important and beneficial. There are many things that you could not do without the force of friction. Walking You could not walk without the friction between your shoes and the ground. As you try to step forward, you push your foot backward. Friction holds your shoe to the ground, allowing you to walk. Consider how difficult it is to walk on slippery ice, where there is little friction. Bear did not heed warning sign Bear did not heed warning sign Writing Writing with a pencil requires friction. You could not hold a pencil in your hand without friction. It would slip out when you tried to hold it to write. The graphite pencil led would not make a mark on the paper without friction. A pencil eraser uses friction to rub off mistakes written in pencil lead. ]

uses of friction
Weegy: Answer: Uses of friction in our daily life activities: Some of the important uses of friction include: Walking And Running Friction makes walking and running possible. [ If there were no friction, we would be unable to move our legs on the ground without slipping and falling, just like you would experience when you try to move on a slippery surface, such as ice, which offers very little friction underfoot. Also, friction enables ... (More)
