质量 Mass

(重定向自Inertial Mass)
上图展示五个互相关联的质量的特性以及将这些特性联系起来的正比例常数。每一个质量的例子,都被认为包含全部的五个特性,然而,由于巨大的比例系数,通常很难确认两个或者三个以上的属性。史瓦西半径(rs)表示物质弯曲时空的能力。标准引力参数(μ)表示一个物体对其他物体施加牛顿引力的能力。惯性质量(m)表示质量对力的牛顿响应。静止质量(E0)表示质量转换成其他形式能量的能力。康普顿波长(λ)表示质量对局部时空几何的量子响应。
阿努比斯正在称量胡夫心脏的重量,公元前1285年。
约翰·道尔顿所着《化学哲学的新体系》(1808)一书中描绘的各种各样的原子和分子。
约翰内斯·开普勒,1610。

在日常生活中的“重量”常常被用来表示“质量”,但是在科学上,这两个词表示物质不同的属性(参见质量对重量)。

在物理上,质量通常指物质在以下的三个实验上证明等价的属性之一:

假设一个质量为M_1的物体距离别的质量为M_2的物体的距离为r
第一个物体受到的引力可以通过所示公式计算:F=G\frac{M_1M_2}{r^2}
其中,G表示万有引力常数,其值为6.67×10 kgms。这个质量通常被称为引力质量。


从17世纪以来不断有实验证明,惯性质量和引力质量是等价的,这条原理在广义相对论中被称为等效原理。
狭义相对论证明了物质能量E和其质量m之间的关系(E=mc^2)。根据这个关系,一个由许多粒子构成的集合体,其质量可能大于也可能小于这些粒子单独的质量之和。

Mass 质量

(重定向自Inertial Mass)
The kilogram is one of the seven SI base units and one of three which is defined ad hoc (i.e. without reference to another base unit).
The relation between properties of mass and their associated physical constants. Every massive object is believed to exhibit all five properties. However, due to extremely large or extremely small constants, it is generally impossible to verify more than two or three properties for any object.
 The Schwarzschild radius (rs) represents the ability of mass to cause curvature in space and time.
 The standard gravitational parameter (μ) represents the ability of  a massive body to exert Newtonian gravitational forces on other bodies.
 Inertial mass (m) represents the Newtonian response of mass to forces.
 Rest energy (E0) represents the ability of mass to be converted into other forms of energy.
 The Compton wavelength (λ) represents the quantum response of mass to local geometry.
Depiction of early balance scales in the Papyrus of Hunefer (dated to the 19th dynasty, ca. 1285 BC). The scene shows Anubis weighing the heart of Hunefer.
Galileo Galilei (1636)

In physics, mass is a property of a physical body. It is generally a measure of an object's resistance to changing its state of motion when a force is applied. It is determined by the strength of its mutual gravitational attraction to other bodies, its resistance to acceleration or directional changes, and in the theory of relativity gives the mass–energy content of a system. The SI unit of mass is the kilogram (kg).
