Physics of a Bicycle Kick The bicycle kick is one of the most extraordinary feats in the greatest sport in the world. To perform the kick the player executing the kick has to account for many things such as timing when to jump, determining the trajectory of the ball and many other elements. In the picture above you can see the best player in the world Pelé performing the kick. While in the air there are numerous physics concepts such as gravity, circular motion and the transfer of energy that determine the outcome of the ball and the player. Gravity If you look up the definition for the word gravity on dictionary.com its defines it as "the force of attraction of which terrestrial bodies tend to fall towards the center of the earth. So to break it down nice and simple gravity is a force that pulls down on everything on earth with matter. It basically stops us from floating away into the depths of outer space. If it were not for gravity after jumping the player would just float in the in the air and the ball would also do the same. So without gravity soccer would not be able to be played as it is now.  Transfer of Energy   In order for a player to get into the air to do the movement to perform the kick the energy is required. The player leaps off one leg with is a form of kinetic energy. **Kinetic energy** in simple terms is energy that is in motion. While in the air the player has potential energy. And **potential energy** is energy that is stored because of location. When the soccer ball and the foot of the player come into contact with each other potential energy from the players foot is converted into kinetic energy to the ball. Some energy is also converted into heat energy which is energy that is due to the motion of atoms and he feel as heat. According to the law of conservation energy can not be created or destroyed so if the ball ends up in the directed path, (the back of the net) the kinetic energy from the moving ball is converted into heat energy as it hits the net. That heat energy is then used in the environment for other occurrences. Circular Motion This kick got the name because as the player in the air their legs look as though they are peddling a bicycle. The player jumps straight up and while in the air moves in in a circular motion. They do this in order to gain momentum so that when they strike the ball the ball will travel at a fast speed. media type="custom" key="11757314" align="center" width="130" height="130"
