Physics and Friction
Car accidents happen everywhere. In India, more than 20,000 people die every year by car accidents. Millions die every year over the world, due to the carelessness of the driver and also because of the car. The problem is the the increasement of the mortality rate by road accidents. But science can be applied and used to solve this problem and decrease the amount of mortality rate. Specifically, this can be reduced if we can work on the friction of the surfaces. Not only the friction of the road, but the friction of the tires towards the road. Friction is the scientific solution in order to decrease the amount of mortality rate. Friction can be looked on the pedals of the brakes, the road and also the tires. What is friction? In simple words, friction is nothing but force between two objects as they move over one another, in this case, the tire and road. The better the friction is the better the tires will react. But the friction reacts to one another, so the road and tires both need to have better friction. If not the road, then at least the tires. So the

The friction between the tires of the car or the automobile and the road determine the acceleration and the minimum stopping distance. The coefficient of friction on dry roads is about 0.7 and about 0.4 on wet roads. Generally the tires have a tread design that can be compromised in any weather circumstances. But then again for the best results, the drivers must have different types of tires for different weather conditions. The stats show that the static coefficient of friction in the treaded tires is about 0.7 on dry roads, 0.4 on wet roads, 0.2 on snowy roads, and 0.1 on icy roads. Even though the racing cars have a static coefficient of 0.9 on dry road, it also a static coefficient of 0.1 on wet roads, so it can be really dangerous to drive a racing car on wet
Whiplash is a neck injury that can occur during automobile collisions, when the head suddenly moves back and then forward. These extreme movements push the muscles and ligaments of the neck beyond their normal range of motion. Causes A sprained whiplash neck occurs when the head is suddenly shaken back and forth or suddenly turned hard. This can cause the abnormal elongation of some neck muscles and ligaments (distortion).
Therefore, I focused my research on ways to maximize the potential energy. According to Donald (2018), a larger wheel diameter resulted in a further distance. Donald (2018) also explains that the axle turns once each time the string is unwound; therefore, larger wheels rotate more times than the smaller. I also learned that friction and traction were important variables in this experiment. Too much friction could cause the vehicle to stop sooner; however, not enough traction would result in the car “spinning out” (Inspired Learning).
How does physics involve roller coasters? The meaning of physics is the branch of science concerned with the nature and properties of matter and energy. Six Flags is a great place for families to come together and having fun on all the different types of rollercoasters there are at this theme park. Physics is very well involved in all of the rides at this theme park. Many of the rides have kinetic energy, and centripetal acceleration and so much more.
Heavy rain or snow can cause them to lose control due to the street and cars no longer able to be seen clearly. They begin to lose control from trying to stay on the road, leading to an accident. Since older people have worse vision than younger people, they have a more difficult time driving through the rain or snow. Elderly drivers may also decide to avoid driving during the bad weather conditions, but weather is spontaneous. If bad weather suddenly occurs while they’re driving, they will not be able to stop and immediately lead to panic.
“Roads that had been designed for house transport began to deteriorate under the steadily increasing load of traffic” (Scott). Since the roads were not built for the automobiles, the automobile tires were not fit for the condition of the roads. The tires on the vehicles were very thin and mostly made of wood similar to the early wagon wheels. Because there was more mass of the vehicle, tires had to be replaced often
Nascar racing is one of the most famous competitions of the world and also a national symbol. But, Nasar is more complex than what it seems, in order to win a NASCAR race, the teams behind each car have to cosidered the three D’s (Downforce, Drag and Drafting), These three factors are crucial, and if used correctly it can be the key to win the race. To have a better comprehension of the three D’s, it is necessary to understand what they are and how they affect the racing cars. Downforce Downforce allows the race cars to travel faster through a corner by increasing the vertical force. Nascar glossary states that “air pressure moving over a race car 's various surfaces creates "downforce" or increased weight.
Assessing the conditions around you help to keep yourself as well as others around you safe. Speeding always increases the number of fatalities in collisions. Things to do to avoid fatality include: use time management, monitor your speeding, be careful and stay alert, and slow down according to the situations around you. Driving too fast for conditions usually contribute to traffic violations. Knowing that speeding is most often in correlation to fatalities is a huge eye-opener.
The purpose of the first investigation was to see if someone could survive a fall from an aircraft with a parachute or a raft. The MythBusters created "Buster," who was a fake body used to simulate a real person. For the first trial, Buster was attached to the middle of a raft. By the end, he wasn 't attached anymore and the raft flipped over like a coin in the air. However, the raft was like a parachute so for the second trial, the MythBusters hung Buster from the raft like a parachute.
However, they need to wade through constantly varying conditions of weather and circumstances and have a responsibility to safely transport the most vulnerable group of people, the students. Meanwhile, these skills include driving in harsh weather conditions like rain, low visibility due to fog, etc. as well as driving skills
Almost half of a human 's body weight is composed of muscle. There are three distinct types of muscle tissue: cardiac muscle, skeletal muscle, and smooth muscle. Each of the muscle tissues have different structures, properties, characteristics, and roles in our body. Properties of muscle tissues include excitability, contractility, extensibility, and elasticity. Contractility is the ability to shorten, which causes movement of the structures to which the muscles are attached.
Anything that has motion involved is kinetic energy. The motion can be able to produce kinetic energy. An object that is moving can be able to do work with anything it hits. The conclusion of its motion is the amount of work being done. Kinetic energy can be passed from one object to another by clashing towards each other.
Speed limits are vital to ensure people’s safety, both the driver’s and surrounding pedestrians. The most common cause of road accidents are because of speeding. The higher speed increases the chance of an accident. Enforcing speed limits may help prevent accident that occur on roads. Statistics show the Each year over 700 people are killed in crashes involving someone exceeding the speed limit.
CHAPTER 1 INTRODUCTION 1.1 ABOUT THE CAR A Formula Student car is an opened wheeled race-car designed and fabricated by university level students to compete at global level against other universities. The students involved in such projects conceptualize, design, fabricate, test and race a single seated, open-wheel Formula Style race car. The design of such a car aims at enhancing dynamic performance while maintaining the safety and following the guidelines lay down by the governing body. 1.2
Speeding There are many effects of speeding, such as ticket fees, going to court, driver important class, and a rise in insurance. All of these effects will make you rethink speeding, no matter what the causes for speeding are. Speeding is a very serious matter that could be prevented. Running late, or just wanting to go fast are two of the major causes of speeding.
The cars were also heavy compared to the human weight and as a result could crush the driver if he went straight into a wall. To make it even worse the fuel line may cut and the fire will start burning. The first ever crash recorded was in the year 1919. As a result to this lack of safety there were a lot of tragedies in the racing history. There were more than 35 fatalities from 1953 until today in formula 1 only, some more gruesome than the others.
