Text: In common usage, the mass of an object is often referred to as its weight, though these are in fact different concepts and quantities. In scientific contexts, mass refers loosely to the amount of ''matter'' in an object (though ''matter'' may be difficult to define), whereas weight refers to the force exerted on an object by gravity. In other words, an object with a mass of 1.0 kilogram will weigh approximately 9.81 newtons on the surface of the Earth (its mass multiplied by the gravitational field strength), since the newton is a unit of force, while the kilogram is a unit of mass. The object's weight will be less on Mars (where gravity is weaker), more on Saturn, and negligible in space when far from any significant source of gravity, but it will always have the same mass.

Text: Only the Goal Attack and Goal Shooter are able to score goals directly, and this may only be done from the inside of the semicircle. The job of the Goal Defence and Goal Keeper is to block the Goal Attack and Goal Shooter from shooting; however, they must be three feet or more away from the landing foot of the shooter, otherwise it is called an obstruction. In this penalty situation, the Goal Keeper or Goal Defence must stand by the shooter's side for a penalty pass or shot, and must remain out of play until the ball is thrown. A ball that passes through the hoop, but has been thrown either from outside the circle or by a player other than the two shooters, is deemed a ''no goal''. Furthermore, a shooter (GA or GS) may not shoot for a goal if a ''free pass'' has been awarded for an infringement such as stepping, offside, or using the post.

Text: To maintain lactation, a dairy cow must be bred and produce calves. Depending on market conditions, the cow may be bred with a ''dairy bull'' or a ''beef bull.'' Female calves (heifers) with dairy breeding may be kept as replacement cows for the dairy herd. If a replacement cow turns out to be a substandard producer of milk, she then goes to market and can be slaughtered for beef. Male calves can either be used later as a breeding bull or sold and used for veal or beef. Dairy farmers usually begin breeding or artificially inseminating heifers around 13 months of age. A cow's gestation period is approximately nine months. Newborn calves are removed from their mothers quickly, usually within three days, as the mother/calf bond intensifies over time and delayed separation can cause extreme stress on both cow and calf.
