Watching a weekend football game could be teaching you something
other than who threw the most passes or gained the most yards.
Football provides some great examples of the basic concepts of
physics! Physics is present in the flight of the ball, the motion of the
players, and the force of the tackles. This web page will show you
how physics applies to these areas of football.

What Exactly Is Physics and
What Does It Have to Do with Football?

When you throw a football across the yard to your friend, you are using physics. You make adjustments for all the factors, such as distance, wind and the weight of the ball. The farther away your friend is, the harder you have to throw the ball, or the steeper the angle of your throw. This adjustment is done in your head, and it's physics. Physics is the branch of science that deals with the physical world. The area of physics that is most relevant to football is mechanics, the study of motion and its causes. The three main categories of motion that apply to the game are:

* delivery of a football through the air (pass, punt, kickoff, field goal, extra point)
* runners on the field (backs, receivers, linemen)
* stopping runners on the field (tackling, blocking)


FLIGHT OF THE BALL



When the football travels through the air (long pass, punt, kickoff,
field goal), it always follows a curved, or parabolic, path because
the movement of the ball in the vertical direction is influenced by
the force of gravity As the ball travels up, gravity slows it down until
it stops briefly at its peak height, the ball then comes down, and
gravity accelerates it until it hits the ground. This...

... the amount of force applied:
Less force is required farther out from the center of mass than
closer in. So, by tackling a runner low -- far from the center of
mass -- it takes less force to tackle him than if he were tackled
high. Also, if a runner is hit exactly at his center of mass, he will
not rotate, but instead will be driven in the direction of the tackle.


Similarly, coaches often advise linemen to stay low. This brings
their center of mass closer to the ground, so an opposing player,
no matter how low he goes, can only contact them near their
center of mass. This makes it difficult for an opposing player to
move them, because they will not rotate upon contact. This
technique is critical for a defensive lineman in defending his own
goal in the "red" zone, the last 10 yards before the goal line.

The Physics of Throwing a Football Essay - The physics and science that go into throwing a football are very complicated. You must take into account all of the factors around you, as well as figure out the best angle to send the ball where it needs to be. Throwing a deep ball is all about using the right angle with the right amount of force. I want to find out at which angle is the best to throw the ball the farthest. The angles I will test will be a low angle at 15˚, a medium angle at 45˚, and a high angle at 75˚. The force throwing the ball will be the same and the tight spiral will be assumed constant, so the only factor changing will be the angle at which the ball is being thrown....   [tags: parabola, gravity, football]

Essay on The Physics of Football - The Physics of Football The crowd is cheering as the quarter back from the Chicago Bears throws the football 25 yards to the star wide receiver. As the wide receiver catches the football, he starts off on a mad dash to make a touch down. During his run for the touchdown, he does not see his opponent from the Dallas Cowboys sneaking up on him to stop his success. The wide receiver from the Chicago Bears is tackled by his opponent and prevents him from his victory. While watching this fascinating and suspenseful moment, one would not think that there is more to football than fun and excitement....   [tags: Science Athletics Sports Essays]

Essay on The Physics of Football - The Physics of Football The American Physical Society published an article in January stating that on November 15 th, 1999, on ABC World News Tonight with Peter Jennings, Timothy Gay, professor of physics at the University of Nebraska, Lincoln, stated “Football is a manifestation of physics and it’s something people can relate to. It’s physics in action. My main hope is that somehow I’ll turn some kid onto physics or science in general.”(1) Mr. Gay could not have made a more correct statement....   [tags: Science Athletics Sports Essays]

Essay on The Physics of Football - The Physics of Football There is no question that everything people do in their lives involves physics. This is true from the way we communicate to the way that we fight wars. In some cases the influence of the laws of physics on our world are extremely apparent, such as in sports. Basketball, hockey, baseball and even cricket involve physics. From the most basic motions players perform in the game, to different plays designed by coaches, physics touches it all. These appearances of physics in the games that we play are sometimes so subtle we don’t even notice them....   [tags: Science Athletics Sports Essays]

Essay on The Physics of Soccer - Rolling Motion and Friction Suppose you kick a soccer ball without giving it any spin. Your foot, therefore, gives the ball an initial speed (v) and an initial angular speed of 0. Since grass is not frictionless, the ball initially slides across the field, then starts to rotate and, eventually, starts rolling without slipping. A soccer ball rolls without slipping when its center-of-mass speed equals its angular speed (around its center of mass). OK, now suppose you want to kick the ball so that it immediately starts rolling without slipping....   [tags: physics sport sports soccer football] 734 words

Physics of Soccer Essay - Physics of Soccer I. Introduction Soccer is a sport that’s very challenging and during the course of this semester I’ve found physics can also be described as challenging. As far as I was concerned soccer and physics were both challenging and that was all they had in common, consequently upon researching them both this semester I found that I was wrong. For me this was nothing new because I’ve found that physics isn’t a subject that can be skimmed, but rather it has to be studied to the finest detail....   [tags: Physics Research Papers Compare Football]

Physics of Soccer Essay - Physics of the Ball How and where you kick the ball is the most important aspect within the game of soccer. Lets say you kick the ball perfectly giving it no rotation (or spin), this means that you have given the ball a velocity (v) and an initial angular speed of zero. When the ball comes into contact with the ground it will begin to spin because the ground is not frictionless. The soccer ball will eventually begin to roll without slipping, which is when the balls center of mass is equal to its angular speed....   [tags: physics sport sports soccer football] 1400 words

Essay on Physics of Soccer - What makes the ball curve: Soccer players can make the ball curve by applying a Force, kicking, to the ball that is not in the center of the ball itself. When the ball is struck on the side by a player the ball spins while it is moving forward. In the case of the picture below, the soccer ball was struck on the right side of the ball and is spinning counter-clockwise. What causes the ball to actually curve in the air is a difference in the pressures on either side of the soccer ball. On the left side of this soccer ball, the air is moving faster, than the right side, relative to the center of the ball....   [tags: physics sport sports soccer football] 703 words

Football Players and Chronic Traumatic Encephalopathy (CTE) Essay - Thesis Statement What does Jovan Belcher, Ray Esterling and O.J. Murdock Have in common. They all were famous football players who commented suicide. Each player had something called chronic traumatic encephalopathy or CTE. This is a condition where sufferers have had repeated hits to the head that leads to concussions and ultimately head trauma. In this research paper, we will go over the data about the NFL to see could they have prevented CTE in these players if they had placed the player’s safety first....   [tags: Football Players and Injury]

Physics of a Spudgun Essay - Well it's quite simple actually. Spudguns use some of the same principles as internal combustion engines. Just as burning gas forces a piston out of a cylinder it can also force out a potato. A spudgun is a device that uses some form of propellant to project a potato across the sky. Usually these devices are made of ABS plastic sewer pipe. There are several major parts of the spud gun that these pages will refer to. These parts are the firing chamber, the igniter, and the barrel. The ignition device of a spud gun is simply put the spark generator that causes the combustion of the fuel in the firing chamber....   [tags: physics potato gun cannon] 1916 words
