How to Calculate the G Forces in NHRA Drag Racing
In the sport of professional drag racing gravity takes on an entirely different meaning while accelerating these monsters down the track at speeds in excess of 330 miles per hour. The force exerted on the driver is known as G force. In this short journey down the track, the formula to calculate the forces exerted on the driver will be demonstrated. Next the forces exerted on the driver in the individual classes of cars. Then at the end of the quarter mile G force rears its ugly head again when the parachute is deployed to bring the monsters from their maximum speeds to a stop. In the end does this have an effect on the human body?
To calculate the average acceleration will be derived by converting miles per hour into meters per second. To do this, divide the miles per hour by .6. This will give kilometers per hour. Then multiply that by 1000. This will give meters per hour. This gives meters per hour, to convert this to meters per second divide meters per hour by 3600. At this point divide by the time of the run, this is the average acceleration. Next it is known that gravity makes things fall at a speed of 10 meters per second. Take the average acceleration divided by the time to complete the run and divide this total by 10 meters per second and this gives a number that represents a multiple of gravitational force exerted on the masses involved in the acceleration. This number is a multiple of the normal gravitational force exerted on everything on earth.
If the racer weighs 190 pounds and experiences 2.5 G’s their body would feel as if it weighed 475 pounds. This causes a big strain on the body. The exact physical response on the human is not exactly known because studys on pilots show that some can become accustomed to a little higher G force as when they first started the study. Over all it showed that a human would loose consciousness between 8 and 9 G’s. the space shuttle launches at about 3 G’s. Modern fighter jets pulling out of a hard dive can experience about 8 G’s. Under this kind force the blood pools in, usually the wrong, parts of the body. However, the human body can withstand high G’s for very brief periods of time.
Acceleration and velocity are mostly dependent on the number of dogs, the quality of the dogs, and how well the dogs have been trained, but it also can depend on friction and inertia. The lager mass an object has the the more weight it has and the more inertia it has.
Though physical exercise and training such as running can serve as valuable to the human body it can also come with downfalls as well. Running typically involves with using the lower part of the body such as the legs, knees and joints. This causes a runner to put most of its weight on the lower part of the body which eventually causes complications.“A runner usually is putting the weight down incorrectly on the lower body due to poor foot and lower body placement, this causes a person that may be 120 pounds to put double the weight on the lower body”(Davis). The extra pounds exerted to the body can cause problems such a damaged cartilage, tearing, and swelling. “Marathon runners tend to have the most problems with this because they put so much on their body physically for long...
Some say this can’t be in the Olympics because it's way too dangerous. But what about bobsledding and boxing. Reto Capedrutt died in a bobsledding accident along with 6 others. Carlos Barreto died from boxing injuries along with 9 others. The Olympics have had over 59 deaths from establishment. In total, NASCAR has had only 19 deaths from when it was
Speediness, adrenaline, and the beauty of mind and body combine with a machine. Every racer lined up at the starting gate with their steel horses to achieve the desire of winning. These are some words that try to described what supercross is about, but is not even close to what really is. Over the years I have known people that don’t know anything about supercross; they believe that is an easy sport that just twists the throttle and hold on to the bike. For some, it might not even be consider as a sport because they believe that engines are not a sport. These kind of people will say that supercross does not requires any technique or much skills as others sports without engines. Here is some background information to my reader to get familiar with the sport. Supercross is an indoor sport that takes places in different stadiums around the US. In this races racers risk their life every time they are at the starting gate to win racers and finally to win the championship and be the fastest rider in the US. Through this essay I will provide fears, misperceptions and misunderstandings from people who don’t know about supercross. Secondly, I will respond to their claim with strong arguments and personal experience. Finally, I will construct a convincing conclusion where I will try to open the eyes to my audience, which are people who don’t know about supercross.
Running is a very simple task, all it is is rapid leg movements, along with arm swinging, through long strides while on foot. To be considered an act of running, both feet must be held off the ground at regularly spaced brief intervals. Believe it or not, there is actually a lot of physics behind running. There is the speed of the runner, the length of each stride the runner takes, the energy you use and how to save it, and then you have the pendulum law.
m= 10km2 x 1000m x 1000m = 107m2 107m2 x 15= 1.5 x 1.8m3 = 1.5 x 1011kg
Some high schools require athletes to submit to random chemical testing for illegal drug use. On the other hand, other schools and coaches believe that random drug testing is stating that all athletes are guilty of wrongdoing instead of believing they are innocent. There can be advantages and disadvantages to both sides, although random chemical testing for illegal drug use is the smartest idea. Having random drug tests is used for precautions, influences some to not do drugs if they are considering it, and encourages students to be their best.
Thesis- When the Beatles first stood on the American stage on February 9th 1964, culture and emotions were altered because of the influential music style and “style” the four brought with them to America and how that eventually transformed the attitudes and style of many Americans.
A large majority of people in the United States will say that they are in favor of equal rights for homosexuals. They will all agree that homosexuals should have the same rights in housing, jobs, public accommodations, and should have equal access to government benefits, equal protection of the law, and other rights granted to US citizens. However, when the topic of marriage arises, all the talk of equality ceases. Over fifty percent of all people in the United States oppose homosexual marriage, despite the fact that most are otherwise supportive of homosexual rights. This means that many of the same people who are even passionately in favor of homosexual rights oppose homosexuals on this one issue. This is because there is a lot of misunderstanding about what homosexuality really is, as well as the erroneous assumption that homosexual people enjoy the same civil rights protections as everyone else. For the reasons of ending social injustice, the economic and social benefits of allowing homosexuals to marry, and the constitution, homosexual marriages should be a legalized institution.

Second, the force providing the change in motion is primarily the result of a rapid change in acceleration of the objects involved (assuming the players’ individual masses remain constant.) If we are to a...
Drug test are a positive reinforcement in helping students. Helping students find their full potential are a schools main goal. If random drug test would have been applied sooner at County Academy, Ron probably would have not had to suffer through drug addiction. If students would understand those drug tests are actually there to help them, they wouldn’t fear taking a drug test. Drug test are a positive reinforcement.
In Newtonian physics, free fall is any motion of a body where its weight is the only force acting upon it. In the context of general relativity, where gravitation is reduced to a space-time curvature, a body in free fall has no force acting on it and it moves along a geodesic. The present article only concerns itself with free fall in the Newtonian domain.
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.
