What is the physics behind banana kick (football)?
535927
The football is under the laws of projectile motion which is governed by the laws of gravity. However, in reality, it is much more complicated. It also involves air resistance and the ball's spin.\n\nIf you thing of air itself as a kind of "road" (a soft road), then it is possible to "drive" on this soft road by spinning. So in truth, there is a path that the ball is heading, that is the projectile motion. BUT, there is also another motion that the spin is moving on the "soft air road" which will make it deviate from the "projectile path". The greater the spin, the greater the deviation.\n\nAdditionally, if one can time a spin such that it influences the ball up to a certain point and then stops influencing it (the spin stops in mid air), you can imagine that kind of trick this can have on the ball's motion. It may travel along a path and suddenly deviate from it (for example, like a dip). So the motion of the banana kick can take on very curved paths, depending on the skills of the player who knows how to manipulate contact with the ball itself, resulting in the desired spin, velocity and terminating conditions of the ball's trajectory.

just some heel to toe action. it's alot faster then you think, that's what creates the allusion of defining gravity.

The degree actually depends on many factors.\n1. The position of the person kicking the ball.\n2. Is air resistance taken into account for your question. \n   If not, you can model the motion of the ball by making a\n   few assumptions eg.the ball is modelled as a particle. \n   Then, assume it follows a trajectory path and the ball\n   moves in the same plane throughout the motion. Apply the\n   formulas for kinematic motion.\n3. From the view of Physics, relate it with Bernoulli's \n   Principle.

As the ball hits the ground, its momentum causes its elastic body to compress itself against the ground until enough force had been applied through enough distance to cancel the momentum of the ball and bring it to a stop.  At the instant the ball comes to a stop, it has energy stored in it due to the compression of its body against the ground.  This compressive energy is then released in pressing against the ground, causing the ball to accelerate upward.

While I can not say for certain if a kicker has completely missed the ball, if they were to do so, the ball would still be live so the holder would be able to run or throw the ball.  Often times fake field goals are set up like this.  The kicker will go through all of his motions including the swing of his foot in an effort to draw the attention away from the holder.  The holder will then get up and either run or pass the ball or in some instances quickly toss the ball to another player while still on his knee.

Trap the ball against the heel of one foot with the other.  Roll the ball up the first foot with the second then lean forward and kick the ball back and upward over your shoulder.  \n\n\nMore detailed description here: http://www.ehow.com/how_8849_rainbow-kick-soccer.html\n\nLinks to a video of it below.

Ball starts in the middle(generally theres a drop-in hole on the side). Obviously you try to kick it into the other goal.

There is a coin toss to determine who gets to recieve the ball and who kicks it off. Then there is a kickoff where one team kicks the ball to the other team and they recieve it, then they can run it up the field or call for a fair catch, or if its in the endzone, take a knee and start with the ball at their own 20 yard line.

The very earliest form of the game for which there is scientific evidence was an exercise of precisely this skilful technique dating back to the 2nd and 3rd centuries B.C. in China. \n\nA military manual dating from the period of the Han Dynasty includes among the physical education exercises, the "Tsu'Chu". This consisted of kicking a leather ball filled with feathers and hair through an opening, measuring only 30 - 40 cm in width, into a small net fixed onto long bamboo canes - a feat which obviously demanded great skill and excellent technique. A variation of this exercise also existed, whereby the player was not permitted to aim at his target unimpeded, but had to use his feet, chest, back and shoulders whilst trying to withstand the \n\nattacks of his opponents. Use of the hands was not permitted. The ball artistry of today's top players is therefore not quite as new as some people may assume. \nAnother form of the game, also originating from the Far East, was the Japanese Kemari, which dates from about 500 to 600 years later and is still played today. This is a type of circular football game, far less spectacular, but, for that reason, a 'more dignified and ceremonious experience, requiring certain skills, but not competitive ' in the way the Chinese game was, nor is there the slightest sign of struggle for possession of the ball. The players had to pass the ball to each other, in a relatively small space, trying not to let it touch the ground.\n\nThe Greek game "episkyros", relatively little of which has been handed down, was much livelier, as was the Roman game "Harpastum". The latter was played with a smaller ball with two teams contesting the game on a rectangular field marked by boundary lines and a centre-line. The object was to get the ball over the opponents' boundary lines. The ball was passed between players and trickery was the order of the day. Each team member had his own specific tactical assignment and the spectators took a vociferous interest in the proceedings and the score. The role of the feet in this game was so small as scarcely to be of consequence. This game remained popular for 700 or 800 years, but, although the Romans took it to England with them, it is doubtful whether it can be considered as a forerunner of contemporary football. The same applies for hurling, a popular game with the Celtic population, which is played to this very day in Cornwall and Ireland. lt is possible that influences were asserted, but it is certain that the decisive development of the game of football with which we are now familiar took place in England and Scotland.\n\nThe game that flourished in the British Isles from the 8th to the 19th centuries had a considerable variety of local and regional versions - which were subsequently smoothed down and smartened up to form the present day sports of association football and rugby football. - They were substantially different from all the previously known forms - more disorganised, more violent, more spontaneous and usually played by an indefinite number of players. Frequently, the games took the form of a heated contest between whole village communities or townships - through streets, village squares, across fields, hedges, fences and streams. Kicking was allowed, as in fact was almost everything else. However, in some of these games kicking was out of the question due to the size and weight of the ball being used. In such cases, kicking was instead employed to fell opponents. Incidentally, it was not until nine years after the football rules had been established for the first time in 1863 that the size and weight of the ball were finally standardised. Up to that time, agreement on this point had usually been reached by the parties concerned when they were arranging the match, as was the case for the game between London and Sheffield in 1866. This match was also the first where the duration of the game was prearranged for one

Precision amidst chaos.\n\nNo other sport has it to the degree of American Football.\nOne finger can change the course of a game in which 250lb + men are colliding at full speed.

To play the game of football (American), strength is a key factor, as many different facets of the game are based on trying to control the movements of other players -- be it through blocking, running or tackling. And while technique and leverage are key aspects of this, they can only compensate for so much if one player is significantly stronger than the other. So yes, to be successful, I would say strength is a key factor in the game.\nThe one exception to this might be the role of kicker or punter, but each of those also need strong legs, which would again go back to the need for strong muscles.\nHope this helps.

It's just like football, except the players wear belts with small strips of paper on them. When the defenders pull off the belt, then it is just like a tackle. The play is then dead

and this relates to football??? How!!!

a penalty kick is a real pain for the defending team and a nightmare to the shotstopper unless he saves it..\n\npenalty kick is awarded when the players of the defending team commit a foul inside the 18 yard box....\n\nthe foul is not specific, the situations which can attract this are, clumsy or dangerous tackles, shirt pulling, dangerous movements (physical), elbowing, pushing, handling the ball, fake fall by the defender etc....\n\nin some, not so very hard up situations the referee can choose to give the attacking team an indirect feer-kick inside the 18 yard box as well...\n\nthe severity of the situation determines the type of kick which is most dominated by the former.. also to get a penalty shot the foul has to be commited inside the box..

Believe it or not, the dropkick remains a legal maneuver in the National Football League today. Although the dropkick has not been successfully converted on an NFL gridiron in decades, mention of it still exists in the NFL's official rule book. Rule 3, Section 8 defines the dropkick as, "a kick by a kicker who drops the ball and kicks it as, or immediately after, it touches the ground."

when football was first invented it was similar to soccer and rugby, the early games where played by using a variety of techniques to score, a drop kick like what we saw doug flutie this year attempt on a extra point was rampent in the early years of the sport.  drop kicks were used so much in the early days and were worth two points.  most teams would settle on a drop kick to get points easily, but then the ball was more round like a soccer ball. the evolution of the american football evolved through testing to see how you could throw a ball further, now it has evolved into the passing and rushing game we see today, but years in the past the dropkick led the sport to be called football, rumor had it that while the inventor was visiting mexico he heard a word about the sport soccer or rugby being callef futbol and then brought the word back and dubbed american football.
