The Physics of Automobile Accidents
Automobile accidents happen all around us. We see cars in the middle of the road after just rear ending each other. We see cars driving around town with big dents in them. Do you ever stop to wonder how car accidents happen? Physics; that’s how they happen. There are several aspects of physics that apply to automobile accidents.
An aspect of physics that is applicable to automobile accidents is kinetic energy. Kinetic energy can be defined as the energy of motion. The equation for kinetic energy is:
KE=1/2mv^2
Kinetic energy behaves a bit differently depending on the type of collision: elastic or inelastic.
In an elastic collision, kinetic energy is always conserved. Nearly all of the kinetic energy is transferred from the first object to the second. Thus, when two cars collide, all the kinetic energy would be conserved; no energy would be lost. The objects in an elastic collision “bounce” apart when they collide. The only time that an elastic collision occurs in an automobile accident is when the vehicles collide at a slow sp...
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).
This week’s readings of the reviews of Spike Lee’s ‘Do the Right Thing’ and Marilyn Fabe’s “Political Cinema: Spike Lee’s ‘Do the Right Thing’, raised a number of questions regarding not only the moral issues the film addresses but also the intention of the artist. This dialectical opposition, which Pamela Reynolds suggests “challenges the audience to choose” (Reynolds, p.138) between the narrativized hostility shown between that of the hero and villain. More specifically Lee’s portrayal of violence vs passive opposition. This can be perceived through Lee’s technical employment of contradictory quotes from Martin Luther King, Jr and Malcom X at the conclusion of the film, which not only highlights this concern but also deluges further into themes of political opposition. Marylin Fabe discusses this where she states that Spike Lee’s film carries a “disturbing political message” (Fabe, p.191). Arguably, ‘Do the Right Thing’ acmes themes of racism (Black vs White); with underlining motifs of imperialism (colonisers’ vs colonised), psychoanalytic (power vs powerlessness) and even Marxist theory (ownership vs public space/consumption), with Clarence Page stating that Lee provides a “public service… (not trying) to provide all the answers, but raising the questions.” (Reid, P.144). In saying this we explore this concept of the role of the artist, with Georgopulos stating that the role of the artist is to create a consciousness within the audience by revealing a fraught set of truths about the human condition. Thusly, the reactions and responses to the films reveal Lee to be successful in conveying his intentions, which back in its zenith, explored this issue of racism in a way that had rarely been seen, and presented the ways in which t...
Shelton Jackson Lee was born in Atlanta, Georgia March 20, 1957. Born to teacher Jacqueline Carroll and jazz musician William James Edward Lee, Shelton grew up in Brooklyn, New York where he was provided with a rich cultural upbringing that included plays, movies, and music (Gale 1). At a young age, Lee was nicknamed “Spike” by his mother who noticed his rough nature and the nickname stuck well into his adult life. He attended Morehouse College in Atlanta, Georgia where he gained an interest in film and then graduated with a Bachelors degree in Mass Communication. Lee went on to attend New York University’s Tisch School of the Arts where he created his first student film and graduated in 1982 with a Master of Fine Arts in Film and Television. Being one of the few black students to attend Tisch School of the Arts, the aspiring filmmaker’s first year at New York University was a particularly difficult one. Lee’s experiences, race, and upbringing have all led him to create controversial films to provide audiences with an insight into racial issues.
An elastic collision between two objects is one in which total kinetic energy (as well as total momentum) is the same before and after the collision.
A tension pneumothorax can be caused by a blunt or penetrating trauma, in the case study provided it would be a blunt trauma. The trauma to the chest area causes damage to the plural cavity; either the visceral (lines either lung) or parietal plura (lines the thoracic wall), or can be caused by trauma to the traceobronchial tree (Daley, 2014). The trauma to the chest area causes the formation of a one-way-valve, this allows for the air to flow into the plural space on inhalation, but on exhalation cannot be expelled (Curtis, Ramsden, & Lord, 2011). As the trapped air in the lungs build up within the affected side it can cause serious complications. In the case study it is the left lung that is in distress, and as the pressure increases within the left lung it can cause an impaired venus return to the right atrium (Daley, 2014). The increased pressure can eventually affect the right lung as the pressure builds in the left side and causes mediastinal shift which increases pressure on the right lung, which decreases the patients ability to breath, and diffuse the bodies tissues appropriately. The increase in pressure on the left side where the original traum...

Spike Lee is brand name when it comes to the film industry. When you try to ask any group of people their opinion about this man, you will probably receive numerous positive responses from the film community as well as the African American community. Do the Right Thing (Spike Lee, 1989) is a film that illustrates how racial conflict can become a reality while showing the repercussions that come with racial segregation. Spike Lee uses a number of tools to write and produce the film in order to ensure the message reaches his intended audience in the best way possible. The use of location, soundtrack, and dialogue is abundant in this film. Therefore, this film analysis paper is for Spike Lee’s Do the Right Thing (1989). It is a film in which racial segregation ignites riots in a neighborhood dominated by the black population. The heightened scene of this film analysis is where Spike Lee throws a trash can and it is from this that hell breaks loose and riots begin.
Tension Pneumothorax requires immediate attention. A needle or chest tube needs to be inserted into the chest cavity to release the pressure as soon as possible. If an evacuation is going to take a long period of time you may have to do this procedure yourself. That is not recommended though.
The film Do the Right Thing was directed by Spike Lee and came out in 1989. Not only did Spike Lee direct it, he starred in the film playing the character Mookie. The film addresses racism and police brutality problems in our society, and watching this film 26 years later, one can still relate to these problems today. Do the Right Thing still impacts today, because what happened in the film and what the film addresses still happens today throughout America. Even though times have changed some things haven’t changed as much as we thought it would.
Due to the strong and growing evidence in scientific literature on the beneficial effects of physical activity on health and well-being, the importance of Clinical Exercise Science has increased. Physical activity is defined as any bodily movement produced by skeletal muscles that requires energy expenditure. Exercise, is a subcategory of physical activity that is planned, structured, repetitive, and purposeful in the sense that the improvement or maintenance of one or more components of physical fitness is the objective (http://www.who.int/dietphysicalactivity/pa/en/; last accessed on 30 April 2016). Generally speaking, Clinical Exercise Science is an applied clinical branch which deals with the application of various exercise modalities for
When you drop a basketball, or any ball in general, it bounces back up. But how high does it bounce? If there is no other outside force acting on the ball such as a hand pushing down on the ball, the ball’s bounce will decrease each time it bounces until it eventually stops bouncing. The way the ball bounces is due to momentum and energy. Each time the ball bounces, it seems to lose energy because the height decreases by each bounce. However, the energy is not really lost, but rather transferred or changed. A bouncing ball has two main types of energy: kinetic and potential. Kinetic energy is the energy an object has due to its motion. Every moving object has kinetic energy. Potential energy is the energy stored in an object due to its position. The higher the object, the more potential energy it has. Each time the ball bounces, the ground absorbs some of its energy, which is why different surfaces cause the ball to bounce at different heights. Soft surfaces such as carpet absorb more energy than hard surfaces like concrete or wood. This causes the ball to bounce lower than when it is bounced on hard surfaces like concrete.
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.
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...
