In order to explain how air pressure drops when the temperature does you would need to use the concept of the ideal gas law. This states that pressure times volume is equal to the amount of gas times the ideal gas constant times temperature. This formula proves that when it is cold, the pressure in a football decreases, causing it to naturally deflate itself. (Florio,2015) If footballs are inflated indoors and they are brought outside in a fifty degree environment then the pressure in a ball will drop when it starts to cool off. It would take no more than half an hour for the temperature inside the ball to be even with the temperature of the air on the outside. If the Patriots had filled the balls to twelve and a half PSI, pressure per square inch, in a seventy degree area then the PSI will drop by one after thirty minutes (Andrade, 2015.) …show more content…
Healey moistened the footballs because during the game it was roughly fifty degrees and there was a large shower of rain. When he did this the PSI dropped by about two, just like the Patriots' footballs that went from twelve and a half to ten and a half. More evidence also proves that some academic and research physicists now admit that they made an important mistake in their original calculations. After the error was fixed the amount of deflation predicted in moving from room temperature to a fifty degree field is roughly doubled. Healey measured the drop in twelve footballs that were moved from a seventy-five degree room to a fifty degree area, just like the Patriots. (Glanz,
When there is a heat exchange between two objects, the object’s temperature will change. The rate at which this change will occur happens according to Newton’s Law of heating and cooling. This law states the rate of temperature change is directly proportional between the two objects. The data in this lab will exhibit that an object will stay in a state of temperature equilibrium, unless the object comes in contact with another object of a different temperature. Newton’s Law of Heat and Cooling can be understood by using this formula:

Football, specifically NFL football, has become a staple of the annual holiday, something the NFL is keenly aware of.
How football began, the first American football game was played on November 6, 1869. The Rutgers vs. Princeton played the first game (Bennett). Walter Camp introduced the line of scrimmage and down and distance (Bennett). The first professional “league” was the Ohio League (Bennett). The American Football League (AFL) started in 1960 (Bennett). The first Super Bowl was in 1967 and the Green Bay Packers defeated the Kansas City Chief (Brooks and King). The Houston Oilers defeated the Los Angles Charges in the first AFL championship (Brooks and King). Considered one of the greatest coaches, Vince Lombardi, died from cancer on September 3, 1970 at the age of 57 (Brooks and King). Seven days after Lombardi’s death, the National Football League honored him with the name of the Super Bowl trophy (Brooks and King). Franco Harris made the “Immaculate Reception” which lead to the first Pittsburgh Steelers victory for them (Brooks and King). In the 1970’s the Pittsburgh Steelers won four Super Bowls (Brooks and King). In 1978 the National Football League moved from 14 games a season to 16 games (Brooks and King). O.J. Simpson is the first player to rush over 2,000 yards (Brooks and King). In 1981 Ronald Regan said “Football is the last thing left in civilization where men can lite...
Even though football players are aware of the dangers the game can bring upon them, they take part despite it. The passion, the joy it creates; for professionals it’s also the devoted fans and compensation they receive is what keeps the players motivated. Today players are much bigger, faster, smarter, bigger, better. The game is more physical. The sport has never been so competitive. The popularity has reached new peaks, as much that the NFL has thoughts of moving a team to London, England. Additionally, Super Bowl XLVII (47) was one of the most watched television events of all time; an astonishing 108.4 million viewers (The Associated Press). Fans worship their teams and love to see big hits. Football is a contact sport; injuries are no doubtingly part of it. Concussions are one of the many detriments caused by the ruthlessness, but one of the few with perpetual effects: consequence of the brutality.

An object that is falling through the atmosphere is subjected to two external forces. The first force is the gravitational force, expressed as the weight of the object. The weight equation which is weight (W) = mass (M) x gravitational acceleration (A) which is 9.8 meters per square second on the surface of the earth. The gravitational acceleration decreases with the square of the distance from the center of the earth. If the object were falling in a vacuum, this would be the only force acting on the object. But in the atmosphere, the motion of a falling object is opposed by the air resistance or drag. The drag equation tells us that drag is equal to a coefficient times one half the air density (R) times the velocity (V) squared times a reference area on which the drag coefficient is based.
Football is a culture and within that culture is the desire to make money. In the 2014-2015 season, the NFL made $7.24 billion. Many dedicated fans travel to the stadium on a Sunday afternoon to experience the culture of football: the tailgate in the parking lot, the hundreds of dollars they pay to publicly display their favorite team’s gear, the front row seats to the game for them and their best buddy, the hotdogs and beer from the concussion stands. Many fans will participate in the NFL’s lifestyle every week. But the question is, do they really care about the actual sport or is it just the comradery and entertainment that it
Background Knowledge -------------------- Pressure The three scientists Boyle, Amontons and Charles investigated the relationship between gas, volume and temperature. Boyle discovered that for a fixed mass of gas at constant temperature, the pressure is inversely proportional to its volume.
Have you ever wondered why so many NFL players retire at a young age? One of the main reasons why is that football is a very dangerous sport. Football is known to cause serious damage to both the brain and body. Football has terrible long term effects on the brain, there are much better ways to get your workout, and leaves your brain in much worse shape in comparison to the average person.
There are three main energy systems used in a game of touch football which consist of the creatine phosphate (ATP PC) system, lactic acid system and the aerobic system. Each system plays a vital role during game play. Every muscle in your body requires energy to perform all movements, and to do this, the energy is produced by the breakdown of a molecule called adenosine triphosphate (ATP). ATP is found in all cells which is a chemical form of muscular activity and performs mostly all functions in the human body. It contains 3 phosphate groups and adenosine. ATP is stored in the muscles and lasts for approximately 10-30 seconds. Carbohydrates, fats and proteins, are all producers of ATP from the food we eat; however Creatine Phosphate is also a high energy compound producer found in the cells. These three chemical reactions are conducted to continue muscular work. The first system used in a game of touch football is the ATP PC system. This system is stored into the muscles and used in short durations for up to 10 seconds and doesn’t not require oxygen therefore being anaerobic. ATP lasts approximately 3 seconds, and then Creatine phosphate (CP) will continue until all ATP PC energy is used up. The use of ATP is high intensity and would usually be used in a 50m sprint or a pass in touch. Once the CP energy is used up the body then switches to the lactic acid system. This is because of the breakdown of glucose, resulting in the production of lactic acid. The lactic acid system an anaerobic energy system, which lasts for approximately 30 seconds to 2 minutes, and is the conversion of glycogen to glucose. In relation to a game of touch football, the lactic acid system could be used during a quick wruck, as the movements required are a...

Obviously rough and now medically proven to be extremely dangerous, football is dire need of rules and equipment change. Whistleblowers and cover-ups continue to find their way into mainstream media and government documentation, yet the NFL continues to side-step taking responsibility for prior, present day, and future players’
In the modern day United States the sport American football has become not only entertainment but also a tradition whether it’s watching the BCS college championship or watching the super bowl with the family. The sport of American football is unique to the United States and has grown and became iconic over the years and has become a part of many Americans lives. American Football was made in 1869 and was modeled after the sport of rugby. They took the basics of rugby and changed it to make it fit better for them. The game has changed over the years but it also affected many Americans as the tradition of Monday Night football has begun. The game has had problems with the United States government as it was said to be too dangerous to play, this lead to an upgrade in the equipment and they tried very hard to make the equipment well ensuring player safety throughout the sport.
Football is one of the three most popular sports in the United States. The modern game of football most likely originated from England (hornetfootball.org). Walter Camp, a football coach for Yale, is known as “the Father of American Football” because he made several changes to the game of football (historyoffootball.net). The first professional football league was established in 1920, and it was made popular because of the invention of the television. Football is a mixture of science and religion which can be proved in the science of football, the religious interpretation of football, and the players’ use of their religion.
