free fall (disambiguation)
the force known as "weight" is proportional to mass and acceleration in all situations where the mass is accelerated away from free fall. for example, when a body is at rest in a gravitational field (rather than in free fall), it must be accelerated by a force from a scale or the surface of a planetary body such as the earth or the moon. this force keeps the object from going into free fall. weight is the opposing force in such circumstances, and is thus determined by the acceleration of free fall. on the surface of the earth, for example, an object with a mass of 50 kilograms weighs 491 newtons, which means that 491 newtons is being applied to keep the object from going into free fall. by contrast, on the surface of the moon, the same object still has a mass of 50 kilograms but weighs only 81.5 newtons, because only 81.5 newtons is required to keep this object from going into a free fall on the moon. restated in mathematical terms, on the surface of the earth, the weight "w" of an object is related to its mass "m" by , where is the acceleration due to earth's gravitational field, (expressed as the acceleration experienced by a free-falling object).
