From the beginning automobiles have run from various different fuel systems, from steam to the current fossil fuel. As we begin to move towards a more environmentally friendly society, you begin to wonder what will the future hold for the future of transportation. In order to get from point A to point B, typically you need to drive a automobile, “60% if the US transportation emission come from cars and light trucks,”(Union of Concerned Scientist, 2014). Fossil fuel is used to produce the gasoline which powers automobiles in the United States; it is leading form of power supply for transportation. However, there are adverse side effects to the use of fossil fuel, such as global warming, environmental and air pollution. With concerns of growing populations and the concern for the environment has caused vast research into looking for other alternative to power automobiles. Some of those research topics have included the use of electricity, magnetism and electromagnetism in the use of power supply for modes of transportation. Throughout the paper and with discussion of electricity and magnetism, we will learn how there are many different way that physics can provide the various alternatives to fossil fuel systems for transportation.
To begin, it is important for use to have an understanding of electricity and magnetism. Electricity is defined as “a fundamental form of energy observable in a positive and negative form that occurs naturally or is produced. It is expressed in terms of movement and interaction of electrons,” (Merriam-Webester, 2014). When we think of the interaction of electrons, we must think in terms of electric charge, electric field and electric current. Electric charge is summarized as the charge of an ele...

Electricity is an interesting subject. There is so much you can learn from it, like how our lights turn on or how we make cell phones. This is all a mystery until we finally get a little bit of information in our brains. I've just read two articles, "Energy Story" and "Conducting solutions". I also watched a video called Hands-on Science with Squishy circuits. I learned so much valuable information from these resources.
Although most people deem Henry Ford the father of automobiles, most historians agree that the birth of the modern car came about in the 19th century with some previous trial and error designs that led up to what we consider to be automobiles today. Beginning in the late 1700s, European engineers began experimenting with motor powered vehicles. Steam combustion and electric motors had all been attempted by the mid-1800s but had not yet been mastered. Surprisingly, the electric car was the most popular but a battery strong enough to move at more than a few miles per hour had not yet been invented yet. Imagine how different the world would be today if engineers had spent more time on innovating a battery for an electric car rather than creating a brand new engine with emissions which polluted the atmosphere. Automobile pioneers like Ransom E. Olds and Henry Ford c...
A revolutionary environmental impact to pollution is provided by electric cars which produce zero emissions and provide a replenishable fuel resource. Toxic emissions into our earth’s environment would be reduced immediately as gas powered, pollution emitting vehicles are replaced with non-polluting, battery powered vehicles. Not only will pollution be reduced, but the means that power these vehicles are a renewable resource. Electricity can now be created by environmentally safer means, such as hydro-electric dams, wind farms, and various types of power plants proving a sound resource. With a safer, less polluting, renewabl...
Electromagnetism has a history that dates back over 200 years. The year 1700 was the first demonstration of an electromagnet, yet scientists didn't know much about electromagnetism (Bellis 1). In 1820, scientists had just started to get deep into electromagnets, Hans Oersted discovered that a conductor carrying an electric current was surrounded by a magnetic field (Bellis 2). Hans Oersted discovered this because his compass reacted to a battery when he connected them using wires. That is a big breakthrough because they can now make hypotheses about why the wire with current makes a magnetic field to rearrange the compass direction. In 1873, James Maxwell observed the interaction between positive and negative electrical charges (Brian, Looper 2000). Ben Franklin was the person to figure out that there is a positive and negative charge (Bellis 1). Electromagnetism is the branch of physics that studies the relationship between electricity and magnetism. Without magnetism, electricity couldn't exist, without electricity, magnetism couldn't exist.
...t of the electric car for the economic and practical benefits that would reinvigorate the country and make life easier for everyone. Upon revisiting the original question to this essay, the electric car is a worthy solution to our energy crisis and proves to be an economically responsible car. Its long-term cost savings outweighs easily improved flaws. However, in order to better understand the work done by scientists, research must be done specifically on the predecessors to the electric car and determine how those have stood the test of time. This will be done in order to help predict how the electric car will survive in the world. The future may always have a hint of uncertainty, but if scientists, governments, and drivers implement the new car with care, the goal of a smooth transition from fossil fuels to renewable energy sources can finally be achieved.
Environmental concerns have been raised from time to time because of the dependency on the gasoline-fueled engine as the chief auto powertrain technology. This has resulted in exposing many automobile users to unpredictable prices of fuel. These issues were, however, the reason for the inception of Tesla Motors so as to bring into existence another set of automotive which serves the similar purpose; but uses another form of energy that being electricity to drive them instead of the disadvantageous gasoline-powered engine. This invention was influenced by a number of factors in terms of their planning and performance (Hunger, 2010).
Imagine that you’re driving on an open highway in the middle of summer. All you see in front of you is asphalt for miles and miles. The windows are down and your favorite song comes on the radio. You’re behind the wheel of a Tesla Model S, the newest electric car that can go from zero to sixty miles per hour in 2.4 seconds. This will soon be the future of all motor vehicles. Electric cars are beginning to have colossal impacts on our society because of their energy efficiency, performance benefits, and the fact that they are less harmful to the environment. In the near future, electric cars will dominate the road and eventually the planet’s overall need for oil will decrease immensely.
The relationship between electricity and magnetism is that each phenomenon generates a field. Electric fields can be pictured by thinking in terms of gravitational forces. Where, any two objects have a gravitational force on one another. Any two electric charges have a force between them (either repelling, or attracting depending on polarity). These electric fields are vector forces, with size and direction at each point in space....
Electricity and electrical components are a major part of our lives today. Our lives pretty much come to a halt if there is a power outage or if our electrical devices stop working, sometimes we even start panicking because we are so dependent on these components that we cannot afford to lose them and their importance and use only increases as time passes. We all use these electrical devices and also electricity itself but most of us do not think about the math and physics that works behind all of these things.
In this case study I will be discussing advantages and disadvantages of electric cars. Electric cars are cars that are powered by electricity. Electric vehicles are an important part of cutting emissions and reducing global warming. The battery of an electric car stores electrical energy. The electric motor is coupled to the wheels through gears; it converts 59-60% of electrical energy into the wheels. The battery runs the motor which allows the car to move. Electric cars are necessary as they will save money, because electricity is cheaper than gas. Also electric vehicles will help reduce global warming and pollution. However, some people say that electric cars still have environmental costs. The electricity used to recharge EV batteries has to come from somewhere in the world, and now, most electricity is generated by burning fossil fuels. Although electric vehicles are classified as green cars, purists will not appreciate the toxicity of the batteries.
First off, what is current. Current is expressed in a unit called Amps. Amps are a measurement of how many electrons pass per second. That is to say, a wire with 40 coulombs passing any point in a 2 seconds would be said to have 20 Amps of current (40 Coulombs (a unit of charge given as 6.24x1018 electrons) / time in seconds or in this case, 2 seconds. The Amp is also known as Coulombs per second) Another trick about current is that it is measured in the movement of the positive charge. Literally that is to say the current moves in oppostion to the electrons. This is because originally it was thought that the positive charge is what moved, both are viable, but in reality a positive charge is generally fixed since within an atom the electrons are migratory, while the protons and neutrons tend to be stationary.
Most people today fill up their car with different qualities of petrol, because that's what the average car takes. They don't usually consider an alternative for the petrol that they load into their cars. Although petrol is widely used, it is not the only source for a car to get its power from; diesel and electricity are alternatives to the general petrol used by most cars. Although different from each other, diesel and electricity are alternatives to the average gasoline received at a gas station. Diesel is a more concentrated type of fuel that is usually used by big automobiles because they require a lot of power in a little amount of time. Electricity is a method that uses the power of batteries to produce a low horsepower but, nevertheless fast automobile. Electric cars are generally created to be soundless and environment friendly. The purpose of this paper is to classify and educate the reader of the different types of fuel available for an automobile to use: petrol, diesel, and electricity. The general petrol, used by most people, is usually the only type of fuel accepted on the average car in the United States today.
Electric currents produce magnetic fields, they can be as small as macroscopic currents in wires, or microscopic currents in atomic orbits caused by electrons. The magnetic field B is described in terms of force on a moving charge in the Lorentz force law. The relationship of magnetic field and charges leads to many practical applications. Magnetic field sources are dipolar in nature, with a north and south magnetic pole. The magnetic field SI unit is the Tesla, it can be seen in the magnetic part of the Lorentz force law F magnetic = qvB composed of (Newton x second)/(Coulomb x meter). The smaller magnetic field unit is the
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.
Transportation is one of the basic necessities of human civilization. If there is no transportation on land, sea, or air, there may not be communication between human beings on this planet. But there are also side effects of transportation, which includes pollution. Pollution means the harmful wastes produced by humans which damage our environment in many ways.
