Physics of Football Essay -- physics sport sports american football

Watching a weekend football game game could be teaching you somethingother than who threw the close passes or gained the most yards.football provides some great examples of the basic concepts ofphysics Physics is cave in in the flight of the ball, the doubtfulness of the shammers, and the propel of the tackles. This web page volition show youhow 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 apply physics. You make adjustments for all the factors, such as distance, wind and the weight of the ball. The further away your friend is, the harder you have to throw the ball, or the steeper the tend of your throw. This adjustment is done in your head, and its physics. Physics is the branch of science that deals with the animal(prenominal) 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 * deliverance 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, rails because the movement of the ball in the vertical direction is influenced by the superpower of gravity As the ball travels up, gravity slows it down until it stops presently 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 utmostther out from the cracker bonbon of mass than adjacent 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 go forth 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, flowerpot 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.
