The Physics of an Electric Car
Cannon returns home from work on an average day. He gets his things and trudges into the house, thinking about the events of the day. He relaxes for the evening, thinking about the good things in life. He is lucky that he has a good job, a nice house, and a nice car. But wait, it feels like he forgot something today. His mind races, did he forget a project at work? He couldn’t have, he works so hard to keep up. Not thinking of what he forgot, Cannon stumbles to bed for much needed rest. About three o’clock, Cannon shoots out of bed. He remembered… He forgot to plug in his car. Will there be enough power in the batteries to get him to work? How in the world does that car work anyway?
During the past few years, there has been an increasing concern over our use of gasoline in cars. There are a few answers to this concern. One of the first and most viable answers is the electric car. These vehicles are made up of a few components that help them run just like a normal car. The components to a direct current (DC) electric vehicle are the batteries, the controller and potentiometer, the motor and a specialized
One of the major problems with electric vehicles is storing enough energy to supply the motor over an extended range. The average distance for an electric vehicle is 50-100 miles. Batteries are the energy source for our vehicles. “Most electric cars use lead-acid batteries, but new types of batteries, including zinc-chlorine, nickel metal
hydride, and sodium-sulfur, are becoming more common” (Encarta, car). In most vehicles, storage for batteries is a problem. It takes a lot of room for the batteries. It takes between 16 and 50 batteries to get enough energy stored to go any distance.

...ssed and turned all night. He wondered if he would have enough battery power to get him to work on time. Turns out he did have enough to get to work. He spent the next day looking into what made his car run. He realized that there are only a few major components to his electric vehicle: the batteries, the controller and potentiometers, the motor, and the regenerative braking system. What a great way to travel!

The Automotive, or electric car industry particularly, comprises all those companies and activities involved in the manufacture of electric motor vehicles (EV), including most components, such as engines, bodies and rechargeable batteries or another energy storage device. The industry’s principal products are passenger automobiles. Despite the fact that the first electric cars were produced in 1880s , the advances in internal combustion engines, especially the electric starter, soon diminished the relative advantages of the electric car and became the dominant design in the market. Due to this the EV was almost a forgotten industry staying in the early stage of development, conforming to less than 1% of the automotive stock
I believe governmental power is maintained through oppression and tactic compliance of the majority of the governed struggle and conflict are often necessary to correct injustice.
Benjamin Franklin, one of the founding fathers of the United States, once said “Those who would give up essential liberty to purchase a little temporary safety, deserve neither liberty nor safety.” In America’s society today, some are willing to sacrifice their civil liberties in order to gain protection and security over some potential threat. Especially after the events of September 11th and several attempted bombings in U.S. cities. This sacrifice of individual freedoms such as the freedom of speech, expression, the right to information, to new technologies, and so forth, for additional protection is more of a loss than a gain. Citizens of the United States deserve equal liberty and safety overall, as someone should not have to give up one value in order to gain another. This concept of individual right goes beyond the simple idea of “individual comfort.” Personal liberties cannot be surrendered and are not to be compromised since these liberties are intangible. Individuals should not have their personal liberties exchanged for national security because individuals are guaranteed protection to these rights.
...sive republic the chances of a group of people being oppressed is greatly decreased and by examining four policy events that is evident.
There are two subjects essential to this warning, the oppressive overbearing authority and the people who are willing to sacrifice their liberty for security.
In Visual Pleasure and Narrative Cinema, Mulvey states that, “Traditionally, the woman displayed has functioned on two levels: as erotic object for the characters within the screen story, and as erotic object for the spectator within the auditorium, with a shifting tension between the looks on either side of the screen.” (Mulvey 40). A woman’s role in the narrative is bound to her sexuality or the way she
This essay argues that the film Bridesmaids transcends traditional representations of feminine desire that exhibits women as spectacles of erotic pleasure, through the symbolic reversal of gender identity in cinematic spaces. By discussing feminist perspectives on cinema, along with psychoanalytic theory and ideological narratives of female image, this essay will prove Bridesmaids embodies a new form of feminine desire coded in the space of the comedic film industry.
The future American commuter will undoubtedly have to transition from the use of fossil fuels to new alternatives due to the diminishing availability of the nation’s oil resources. How will America respond to this upcoming issue? It is difficult to predict which alternative fuel source America will ultimately choose, but with the premier of Nissan’s electric powered Leaf and other companies; such as Tesla Motors and Chevy, with their electric cars ready for market, the electric car may be winning the race to become the new standard for the gasoline alternative. Electric cars resolve long standing environmental issues, but it will need to maneuver around many roadblocks to become a marketable consideration for the general public. The cost of electric cars, currently on the market, makes them an impractical purchase for the average consumer. If cost is not the growing concern in today’s economy which prevents the consumer from considering this option; they may deny the technological advance due to battery storage capabilities and the inadequate infrastructure in place to refuel and provide for them.
Shel Silverstein, though shaded from the public eye, was a well known author, poet, illustrator, songwriter, photographer and musician. His poems told the story of incredible people, places and animals from around the world of the imagination. He had a following of millions, yet was very secretive about his life. He had many tragedies take place in a short while, not affecting his professional life enough to hinder him from still creating some of the most unusual and wild poems and stories ever told. He is still recognized as one of America’s best poets and was honored by many awards. Shel Silverstein overcame a lot of struggles and still seemed to touch the lives of millions of children and adults all over the world. Shel Silverstein always encouraged his readers to make their own magic, though he was always making enough for all of us to share.
(Gilpin, 2014) According to Tesla, the efficiency of electric cars is three times that of the traditional gas engine as most energy is lost through the heating process.(Gilpin, 2014) There are two types of electric vehicles in production today, BEV’s and PHEV’s. BEV’s or Battery electric vehicles run solely on energy stored in a battery that is recharged at stations. These cars have an operating range of 60+ miles and take about 6-8 hours to recharge at a station.(Gilpin, 2014) Those who need to travel more than 60 miles in a day could face problems with this. Those that may need to travel much farther in a day would be wise to choose the PHEV’s or the plug-in hybrid electric vehicle. These vehicles run on both electricity and gasoline. They can run on electricity alone for up to 40 miles until it makes the switch to gasoline acting like a hybrid. This means that after they switch to their hybrid mode, they will use both electric and gasoline powered until they are charged again.(Gilpin, 2014) While in hybrid mode the PHEV’s can run up to 400+ miles before needing a recharge. (Gilpin, 2014) The relevance of electric cars is spiking. Especially in bigger cities that have air quality issues, the demand for transportation with limited emissions will be a huge
...o do not have the ability to cruise or climb fast enough to compete with gasoline-powered cars and accessories, such as air condition or radios, drain the battery even more quickly. Another problem is the power required to recharge their batteries is generated at the same electric power plants that provide electricity for cities and towns.
Jonathan Swift's story, Gulliver's Travels, is a very clever story. It recounts the fictitious journey of a fictitious man named Lemuel Gulliver, and his travels to the fantasy lands of Lilliput, Brobdinag, Laputa, and Houyhnhmn land. When one first reads his accounts in each of these lands, one may believe that they are reading humorous accounts of fairy-tale-like lands that are intended to amuse children. When one reads this story in the light of it being a satire, the stories are still humorous, but one realizes that Swift was making a public statement about the affairs of England and of the human race as a whole.
The average driver doesn’t think about what keeps their car moving or what keeps them on the road, but that’s because they don’t have to. The average driver doesn’t have to worry about having enough downforce to keep them on the road or if they will reach the adhesive limit of their car’s tires around a turn. These are the things are the car designers, professional drivers, racing pit crews, serious sports car owners, and physicist think about. Physics are an important part of every sports and racing car design. The stylish curves and ground effects on sports cars are usually there not just for form but function as well allowing you to go speeds over 140 mph in most serious sports cars and remain on the road and in reasonable control.
Stenquist explains electric cars might get their energy from coal, wind, nuclear, and solar sources; in addition, these capabilities which improve the environment by reducing the detrimental sources. Stenquist (2012) asserts that electric cars can better reduce the global warming emissions from the gases, which result in a cleaner environment (p. 2). Furthermore, the author interviews several people to
There is no doubt that electric cars are the most appealing from of transportation in the world. They provide two of the most important key points of good transportation: reliable and efficient. They are reliable due to their simplicity of their power trains and the advancement of technology they have. They are efficient because they don't use any gasoline and because their motors can pass the zero-emission standard. Even though they may seem like a boring form of transportation, they offer good features that help keep the Earth's air clean and they help reduce pollution.
