The science of how Messi keeps the ball close to himself photo credit: ZaleDesigns Messi is a magician with the ball at his feet. He's in my opinion the best player in the sense that he can control the ball so well, runs so fast with the ball & changes the direction at full speed like it's a walk in the park. For starters he started playing very early (at 3) which is crucial if you want to be a good player. In that aspect, he's God gifted as he had dribble skills which is genetic in my opinion. Height He is short which means a low center of gravity so it's difficult to push him off the ball. That's why we see that anyone rarely can topple him down, instead players much larger than him lose possession to him. So his short height suits his style of play & is a blessing in disguise. Change of pace Messi changes his pace really well. He starts slow and runs directly at the defender which means the defender has to stop & focus on him. When he reac...
Physics - Friction Introduction Friction is result of the irregularities on the two surfaces in contact of each other. The force of friction is dependent on the irregularities of the surface; if it is greater, then the friction will be greater and if it is smooth, then the friction will be lesser. Effectively, the friction is result of the interlocking of irregularities in the two surfaces. If the two surfaces (in contact) are pressed harder, then the force of friction will increase. On a frictionless surface, if an object starts moving, it would not stop ever; Without friction, it is not possible to construct a building. Friction produces heat; when a matchstick is rubbed against the rough surface, it catches fire. Substances Reducing Friction The substances that reduce friction are known as lubricants . E.g. when oil, grease, or graphite is applied between the moving part of a machine, then it creates a thin layer; resultantly, moving surfaces do not directly r...
