Every year, thousands of people lose their lives in car crashes. There are many factors that come into play when a car collision occurs, however only one factor stays constant throughout every single collision, and that is the laws of physics. The laws of physics are the fundamental base of understanding the world we live in, but unfortunately many people seem to be completely oblivious to them. A lot of the time, we try to deny our ignorance to physics but usually end up proving the opposite. For example, how believable is it that someone could have any knowledge of the physics in cars and have a pet and their lap while driving? Or even worse; a child sitting in the front seat not strapped to a seat belt. These are all situations that take place and spark questions and conversations about how people think, however, the real focus should be on why the laws of physics are important to the “era of the automobiles”. Every year people die in car crashes, but every year, that number decreases. With every year that passes by, we gain more knowledge about how to prevent those life-taking events from taking place, and we do that through accident reconstruction specialists. These are the people that dedicate their hard work and knowledge of physics and mechanics to be able to develop the safest environment possible within a car, in hopes of decreasing the amount of damage done during a collision. The results that the accident reconstruction specialists produce are very helpful for the manufacturers and engineers that are designing the new systems in cars. Now, to further elaborate on the physics behind car crashes, it all starts with newtons laws.

In conclusion, there are many factors that dictate the reasoning of why a collision occurs. Whether it be the road conditions, weather conditions, traffic, or the drivers behaviour on the road, the laws of physics stay firm, unchanged, and non negotiable with, no matter what the case may be. Sometimes people say something “defies the laws of physics”, which isn’t possible in most cases. What actually happens is that event demonstrates the extremes, of the law of physics. These laws are quite simple, but are mistakenly delivered to seem complicated. It shouldn’t be difficult for someone to understand why cars stop or bounce off of each other when they collide, and as Albert Einstein once said “It should be possible to explain the laws of physics to a barmaid”.
In a car crash, the more weight there is, the risk of injuries drops (Williams, May Twenty-second, 2015). In most semi truck accidents (about seventy percent of semi truck accidents), when only the semi truck and trailer alone are involved, there are no deaths. But when another vehicle (such as a car, van, or pickup truck ) is involved, about ninety-eight percent of the time there is at least one fatality, which is really low compared to some other means of transportation (such as a train or an airplane) (EJustice, 2012).
I never knew the answer to this question, until I discovered that human cadavers are used for impact studies. In chapter four Roach visits Wayne State University to watch a crash stimulation. During the stimulation they wanted to see how much impact a human shoulder could withstand before serious injury. I never knew that cadavers played a role with car safety. I don’t agree that safer windshields and steering wheels is the result. I do believe it helps and benefits you, but I don’t think that it is the only result. ()
Investigation of the Relationship Between Mass of a Vehicle and Its Stopping Distance Problem The problem to be investigated is "how does the mass of a vehicle affect its stopping distance when brakes are applied?" This problem is related to the conservation of energy and will be investigated through a trolley going down a ramp. A simple trolley will be used to represent the vehicle and weights attached to the rear of the trolley via a pulley system will act as the brakes. Throughout the experiment energy will be transferred into many forms but no energy will be lost or gained. As the trolley is raised it gains potential energy, when released down the ramp this energy is converted to kinetic energy.
The behavioral models of the traffic as a system has been developed and studied for several decades and the core behavioral models, Gipps’ car-following/acceleration model and lane-changing model are more or less enough to predict behavioral outcomes of vehicles in homogeneous traffic conditions with lane discipline. In mixed traffic conditions with weak/no lane discipline however, the behavior of a vehicle cannot be defined separately using the car-following and lane-changing models. The behavior of a vehicle under such conditions is very dynamic – depending on the behavior of other vehicles in its vicinity. Also, there exists a continuous interaction among the vehicles and therefore, every vehicle is influenced by its surrounding vehicles.
[list] We started our patrol from 54th station, where we responded to Traffic Collision, a hit and run situation. Officer Fraser was driving and handling the radio, he did overall great with the response as we were responding code-3 due to the fact that there were reported injuries. Upon arrival, two officers were helping the passanger of wreck out of the car, where we began setting up traffic control with cones. After the scene was secured, I let officer Fraser take care of the statment from the female driver, which he nailed it. He asked all the questions I would've asked and did overall great with the statment, he then checked the CCTV to check the driver who performed Hit and Run. Officer Fraser then proceeded to put up a departmental BOLO
Who’s to blame when the vehicle gets in a severe car accident? Advances in technology, like self-driving cars, will be bad because it causes people to be lazy, it takes away the responsibility of the driver, it takes away the responsibility of the driver, and it can malfunction causing accidents.
Elderly drivers can also misplace a foot and depress the accelerator very firmly. Many accidents caused by incorrect pressing of the ...
Cars are designed to crumple during a collision as shown in Figure 1. This lengthens the duration of the crash so that the deceleration is less intense. Without crumple zones, the deceleration would be too great for humans and is equivalent to over 15 times what fighter pilots endure during training (MinutePhysics, 2015). Therefore, the longer the duration of the crash, the safer it is for the passengers as there is more time for the vehicle to slow down as demonstrated by Figure 2. There are two types of collisions that a vehicle can incur. Elastic collisions and Inelastic collisions. Elastic collisions are observed in low-speed car carshes where the bumper deforms to absorb the energy and then will pop back out. On the other hand, an inelastic collision is observed through a high-speed car crash in which the bumper would completely crumple to stop the vehicle (Townsend,
...ture a risk-taking species. In ancient times we took risks just to eat. Later we took huge risks by setting out in little wooden ships to explore the earth's surface. We continued as we sought to fly, travel faster than the speed of sound and to head off into space. We rely on increasingly more complex equipment and constantly strive to design and manufacture faster and even more elaborate devices. It goes without saying that every effort is made to ensure our "safety"; to keep us from harm or danger. Every time you slide behind the wheel of your vehicle you are taking a risk. Driving is the riskiest activity in our lives. It is an inherently "unsafe" environment. The most perfect vehicles on the best designed highways on beautiful sunny days driven by fallible human beings crash into each other. The only way to drive "safely" (as we are all admonished to do!) is to learn more about the process. Learn more about your vehicle and how to maintain it; learn how to use your eyes to look far down the road; learn to spot problems before they happen; and also learn to deal with emergency situations. In most cases it's the human element that fails. After all, safe is only as safe does.
Richard Petty once said “You’ll got home safe, so drive safe, and stay safe.” Being a racing legend, he is an advocate for safe driving to minimise the cases of road crushes that have been on the rise. He double up as the chairman of the Veterans’ Safe Driving Initiative, the initiative is aimed at guiding the veterans returning from deployment on safe driving tips. It is necessarily important since the infrastructure has changed over time. Another initiative is being run in Minnesota where the teens are guided on the important safe driving tips. Study shows that more crushes are likely to occur in teen driving than veteran driving. It is also evident that young drivers are more likely to cause a crush within six months of passing the driving test and young male are worse than the females in the field.
As stated in the last paragraph as the speed of the car goes up it affects the safety of the driver inversely. One of the new innovations that many auto racing series run is the safety barrier. The safety barrier became more important and looked at after a horrific wreck at Daytona International Speedway on February 22, 2013. The front end of a drivers car sheared off when the car hit the fence and sent parts and pieces of the car into the stands. (Greenberg). After the officials saw the wreck and the horrible aftermath they designed a fence that would keep the c...
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.
This report is based upon extensive library and internet research as well as an interview with Zaman Qamar, performance engineer at General Motors. He is one of the team members for crash and safety department which deals with accidental issues during severe crash.
Next, many people have either died or have been injured in motor vehicle accidents, each year there are about 5 million people injured in vehicle related accidents (The Environmental Impact of Automobiles). Although this all m...
Crumple zones- are a structural feature used in automobiles. They help by absorbing the impact; this is by spreading the impact through parts of the car instead of in the one spot. This reflects back onto law number one, two and three. This is shown when the car hits the object it causes the car to slow down or completely stop (1). The crumble zone would protect the driver because all the energy has been diverted around the car, instead of the one spot. As a result of the cars mass and its acceleration, the force can be calculated (2). When the car crashes it’s most likely that the object w...
