In order for Americans to get the most out of their vehicles, and to decrease the amount of gasoline Americans use, we need to push and test every aspect of the modern day vehicle. According a study done by the United States Department of Energy, approximately 1.2 billion gallons of fuel are exhausted by U.S. motorists each year (Siggerud, 2007). This is over three billion dollars wasted per year.
An experiment done by metrompg.com found that inflating a vehicle’s tires by 7 psi could increase their rolling distance by 12.5%. They also state from another source that fuel efficiency is reduced by one percent for every three psi that a tire is under inflated. This equates roughly to a four percent increase gas mileage when increasing the tire inflation.
Another poster to a forum by the name of Lee posted impressive results to his daughter’s science experiment from school. He noted that they saw over a five mpg increase when they inflated the tires an additional twenty psi from twenty five psi.
In order to get the push our vehicles we will experiment with the inflation of a vehicle’s tires to determine the rate at which the efficiency of the vehicle is improved over the tire pressure increased.
Design
The experiment will involve many different digital and analog technologies to try and get the most accurate results. To start the tires of the car will be deflated to twenty PSI. They then will be driven on for ten miles from a gas station back to the same gas station. The mileage will be accounted for by the TomTom application on an iPad. The same route will be taken with the same driving characteristics. The miles per gallon will be calculated by using the receipts from filling up and the calculated mileage from the TomTo...

Increasing environmental awareness, coupled with a responsible American government and improved technology, have all contributed to the comeback of low-and zero-emissions vehicles in the US. It remains to be seen whether the automakers and oil companies will once again work to halt this progress, or embrace it as the technology of a more responsible future.
oil and gas are used up each year so that Americans can drive at high speeds across the
Automobiles play an essential role in American society. As if being the major means of transportation was not impressive enough, automotives can be seen on T.V., in movies, in magazines, and can sometimes be indicative of a person’s wealth and social status. On average, Americans drive nearly 40 miles and drive for just over 50 minutes driving per person per day (http://www.bts.gov). That means a person spends roughly one-sixteenth of a day driving. It would make sense, then, to make such an essential part of society as efficient, cost effective, and clean as possible. However, that is not the case. As the years have passed cars have actually begun to move away from efficiency. Hawken writes, “[The automobile] design process has made cars ever heavier, more complex, and usually costlier. These are all unmistakable signs that automaking has beco...
Toyota was the first corporation to expose the very first hybrid car, the Toyota Prius. The Prius has been the most commonly profound hybrid since year 2000. The name Prius is virtually tantamount with the word Hybrid, as most would agree with. As demonstrated by their numbers, the Toyota Prius is by far the most well-known, with over one million cars sold solely in the United States to this day. Statistics show that most buyers that pursue this type of vehicle are mostly all for eco-friendly and/or economic trepidations (The Corvallis Advocate, 2012). When the Prius was initially presented, the car was costing Toyota $40,000 to build, and they were selling it for a low cost of just $20,000 at the dealer. Some of the perks this vehicle carries with them is the fact that the Prius does an outstanding job of receiving high gas mileage. Proving a greater MPG of 62, reporters all over the U.S. have met th...

Cars are large objects of great mass which can reach very fast velocities, this can be a dangerous combination if the physics aren’t correct. Seeing as there is over 1.2 billion cars world wide, physicians have put much detail into aspects of cars to make them as safe as possible. In the paragraphs below I will be be briefly discussing different aspects of the everyday automobile and its safety.
This paper is a look at the physics behind car racing. We look look at how we can use physics to select tires, how physics can help predict how much traction we will have, how physics helps modern cars get there extreme speed, how physics lets us predict the power of an engine, and how physics can even help the driver find the quickest way around the track.

Drivers have a lot to do to improve efficiency and longevity of the car. One such thing is the proper tire inflation. Keeping the correct air pressure in your car is very important. Most experts have liked proper tire inflation to giving vehicles an engine tune up. Properly inflated tires can improve the vehicle mileage by almost 3% to 4%.
Today, people use their own personal vehicles to travel more than ever before. Personal transportation is no longer considered a luxury; it is now considered a necessity. The number of cars in the United States has been growing steadily since the 1970s. The number of miles traveled by cars has risen nearly 150 percent, yet the United States population has only grown roughly 40 percent during that time (hybridcars.com, Driving Trends). Although it may seem like we are advancing into the future, in reality, we are moving backwards from the effects these vehicles have on our bodies and the environment. The pollution produced by these vehicles has brought us to the day where we must find other modes of transportation that cause less harm to the world in which we live. Advances in technology have developed hybrid vehicles to try and slow down the amount of pollution. Driving a hybrid vehicle, instead of a conventional gas powered vehicle, can reduce the amount of pollution that affects our lives and the environment around us.
Over the next few decades, the number of automobiles grew exponentially. But in essence there has been no paradigm shift in personal transportation since Henry Ford’s model T. Today’s cars are better versions of what Ford had built almost a century ago. The future, however, looks more interesting. Rapid industrialization and unchecked growth in population has brought to the front a myriad of problems that were unheard of
