Maneh (unit)
The mina (; ; ; ; ; ; ) is an ancient Near Eastern unit of weight for silver or gold, equivalent to approximately , which was divided into 60 shekels. The mina, like the shekel, eventually also became a unit of currency. History Sumerian From earliest Sumerian times, a mina was a unit of weight. At first, talents and shekels had not yet been introduced. By the time of Ur-Nammu (shortly before 2000 BCE), the mina had a value of talent as well as 60 shekels. The weight of this mina is calculated at , or 570 grams of silver (18 troy ounces). Semitic languages The word mina comes from the ancient Semitic root / 'to count', Akkadian , (), / (/), (), . It is mentioned in the Bible, where Solomon is reported to have made 300 shields, each with 3 "mina" of gold (), or later after the Edict of Cyrus II of Persia the people are reported to have donated 5000 minas of silver for the reconstruction of Solomon's Temple in Jerusalem.

In science and engineering, the weight of an object is a quantity associated with the gravitational force exerted on the object by other objects in its environment, although there is some variation and debate as to the exact definition. Some standard textbooks define weight as a Euclidean vector, vector quantity, the gravitational force acting on the object. Others define weight as a scalar quantity, the magnitude of the gravitational force. Yet others define it as the magnitude of the reaction (physics), reaction force exerted on a body by mechanisms that counteract the effects of gravity: the weight is the quantity that is measured by, for example, a spring scale. Thus, in a state of free fall, the weight would be zero. In this sense of weight, terrestrial objects can be weightless: so if one ignores Drag (physics), air resistance, one could say the legendary apple falling from the tree, on its way to meet the ground near Isaac Newton, was weightless.
