A ball is a sphere that is used in games and entertainment.
A ball or ball is a ball that is usually used in various sports and games . They are usually inflated with air, so they are quite light and can be moved or propelled easily.
From the invention of the wheel, human beings understood that there were other ways in which entertainment could be understood ; In this way, the ball emerged, a spherical element that by rotating it could allow them to do different training , such as going after it, passing it from hand to hand, introducing it in a circle and filling their lives with fun. In the beginning, the balls were designed with carved wood and other elements of the time . Later, with the advancement of technologies, new ways to achieve this were known.
History of the ball
Historians believe that the inventor of the ball as we know it today was the Chinese ruler Fu-Hi , who, in the 4th century BC , formed a spherical mass with different roots and covered it with pieces of rawhide. Apparently, the Chinese limited themselves to playing with the ball informally.
Over time, Mesoamerican cultures devised balls that could bounce, using latex and rubber. The Aztecs , Romans, Egyptians and Greeks already had formal ball games.
Different materials, sizes and shapes
It is worth mentioning that depending on the shape of the ball, the size and the material with which it has been designed, it can be used for one type of movement or another. Some balls, for example, do not bounce (such as bowling balls or bocce balls) and others can (such as soccer, handball or tennis balls).
In general, a ball can bounce and do pirouettes in the air thanks to the fact that it has been designed so that, when certain external factors influence it, it moves in a certain way; So much so that if a ball is fully inflated it has more force than if it is deflated and therefore, it can rise higher and make more turns in the air as well.
In sports such as rugby and American football, an oval ball is used.
