Had just invented the ball. The first thing he did with it was simply playing to pass it from hand to hand. Not used in tournaments. Mesoamerican cultures were the first to use bouncing balls, because they invented rubber balls and latex. The existing physical factors influencing the movement of the ball, and the mode and application of the forces for their displacement. These include, but are not limited to: the shape, air, volume, pressure, temperature, material and texture, etc.. The material of which a ball is constructed (see also: Azteca (ball)), both externally and internally also affects the weight, range and bounce it, that is evident in the manufacture of golf balls. The outer texture is a determining factor in the outcome of the movement, such as the seams of the ball used in baseball pitches are used to produce a desired effect. Another example is the ball used in football, where the number of seams and surfaces makes the body a more or less perfect sphere, that is a classic ball hexagons and pentagons, behave aerodynamically different than one that has a number varying surface boundary, that is evident in the ease of use or control a chanfle.Hay be noted that not all balls were round (a round if we only have one side without any edge), although this appears to be ridiculous the first balls were icosahedral forms which permitted "roll" the ball despite having sides.

Although a soccer ball is called "round" is a truncated icosahedron with 12 pentagons and 20 regular hexagons. The faces are not completely flat but slightly curved. All balls used in official competitions must include one of three stamps. FIFA Approved certification being more demanding of the three. For any of these, the balls have to be overcome in a laboratory. This analysis is evaluated for weight, circumference, roundness, pressure loss, water absorption and rebound. [1].
