World Without Friction Essays

We have been learning in class about the force of friction. It has many purposes and causes many problems. On one hand, high friction can reduce efficiency in energy production in power plants as well as engines. On the other hand, without friction, we couldn’t walk, drive, or fly; at least not the way we now do. Your assignment is to think about what a world would be like without friction and to post a one paragraph (200-300 word) description of such a world on this site by Friday, December 2. You also need to reply with some specific feedback (either constructive suggestions or constructive agreement) to at least 2 of your peers by Sunday, December 4. This counts as a homework, and you will be assessed only based on participation (which includes completing your posts on time).

An upcoming quiz will relate directly to this blog assignment, so don’t forget to check in and look at each others comments (and mine if I add some)

Have fun with this!

A World Without Friction Essay

A World Without Friction (603 Words)Although friction may seem like a minor issue, its absence would chance life as we know it. There would be many negative effects of this like not being able to gain traction on any surface and your ipod’s earplugs always falling out. Also, there would be many positive effects, such as eliminating the need for coolant in engines and lubricant in machines. Moreover, the absence of friction would be both bad and good.

Without friction, many obvious things which we take for granted would not function the way we like. Shoelaces would untie themselves, zippers would always unzip (unless they were upside-down), nails, screws, nuts and bolts would work themselves loose, and driving as we know it would be impossible. Objects would be unable to gain traction on any surface. Therefore, the only way to move without friction would be through force of reaction. One would need to push something to get motion in opposite direction. Then even to stop, one would need to collide with something. In short, one would need some mechanism like rockets have to control motion. A larger problem would be that the threat of meteorites would be multiplied immensely (Goulding). Since there would be no resistance as the meteorite entered Earth’s atmosphere, even small meteorites would be able to penetrate our atmosphere and cause immense damage (Goulding). The damage a large meteor would cause would be catastrophic.

Several ramifications that probably don’t come readily to mind are the effects on the human body, thermodynamics and plate tectonics. Without friction, many functions of the human body would not work. Procreation would be impossible as friction is necessary for the male orgasm. Digestion would be impossible as the human body uses friction to digest and move food throughout the body. Under conditions where the coefficient of friction is 0 on all surfaces, the laws of Thermodynamics would be useless (Goulding). Since friction creates heat, without friction there would be no heat, therefore, no laws of Thermodynamics (Goulding). Plate tectonics would also be drastically altered in the absence...

Imagine a World without Time Essay

675 words - 3 pages Imagine a world in which there is no time. When does the man go to sleep? When does the man wake up? When does the man go to work?

Relationships in a World without God

Life in this designless universe raises questions of identity and can cause turmoil between the relationships of the self to others, the self to history, and the self to God. Through the words of existentialist novelists and philosophers...

The invention of the wheel was substantial in...

Ray Bradbury's Fahrenheit 451: A World Without Books

1263 words - 5 pages “There is more than one way to burn a book. And the world is full of people running about with lit matches” (Wikiquote, “Ray Bradbury”). Author Ray Bradbury made this observation in 1979 and his thought has only become more true as time has gone on. Bradbury warns of the possibility of this happening in his novel, Fahrenheit 451. The message of Fahrenheit 451 is more important than ever because today’s book editors, movie critics, and plays...

Living Without Sexism in a Sexist World

1869 words - 7 pages The Reader’s Companion to U.S. Women’s History stated, “Sexism is the cultural assumption that men are superior to women and deserve preference and power over them.” (Bird, 1998) However, as I did research I found that sexism is not always men being superior to women, but also women being superior to men. Of course, this is normally a feeling brought about by actions, words, and perhaps even nothing at all. I believe that sexism is most common...

The Physics of Skiing

A lot of the reason it is so challenging is because of the laws of physics such as gravity and friction. In this essay I will discuss how physics relates to skiing and how this physics makes skiing so fun and challenging. I will also discuss how things like wax and the shape and width of your skis can...
