重力由于地球引力而产生
我先解释gravity 吧。gravity 就是地心引力，也可以叫做gravitational pull，是地球对其他物体所产生的吸引，也就是我们所说的acceleration(重力加速度)，通常就是g（9.81m/s2或）来表示。这个值在相距地球半径之内的距离都是差不多一样的，在距离超过半径后会增加。而weight就是一个物体其本身质量（mas...

Watch with moving dial or display cover that is attached to a weight so that when the watch is being read, the cover moves, due to gravity, to an open position and when not being read moves, due to gravity, to a shut position
In 1901 the third Conference Generale des Poids et Mesures (CGPM) defined the weight of a body as ``the product of its mass and the acceleration due to gravity". In practical terms the weight force corresponds to the gravitational force. However, this gravitational definition of the weight ...
ie.表示地球作用或施加在物体上的力。 "g"系重力加速度(acceleration due to gravity)的符号 是指自由落体在重力的作用下的加速度 不同星球的数值有所不同. 质量与重量不同，重量会因为该物品放置在地心吸力不同地方而起变化；但系同一件物品，无论搬去那里，其质量都不会改变。 有错请原谅.参考...

The concept of weight is essential in describing the force acted by gravity on an object. The weight of a body depends on its mass and acceleration due to gravity {eq}g {/eq}. Quantitatively, the weight is determined from the formula: ...
Weight is the force with which gravity pulls an object towards the center of the Earth. It depends on both the mass of the object and the gravitational acceleration at that location. The standard unit of weight in the SI system is the Newton (N), while in the Imperial system, it is ...
Massis a measure of the quantity of a substance, whileweightis a measure of how a mass acts in a gravitational field. On Earth, where we are exposed to a fairly constant acceleration due to gravity, we don't pay much attention to the difference between the terms. After all, our definiti...
