质量

在物理学中，质量（来自希腊语 μᾶζα "大麦饼，面团块"）是一个物理系统或物体的属性，导致物体抵抗受力而加速的现象和与其他物体之间的相互引力的强度。如质量天平或称重器等仪器利用这些现象来测量质量。质量的国际单位是千克（kg）。

In physics, mass (from Greek μᾶζα "barley cake, lump [of dough]") is a property of a physical system or body, giving rise to the phenomena of the body's resistance to being accelerated by a force and the strength of its mutual gravitational attraction with other bodies. Instruments such as mass balances or scales use those phenomena to measure mass. The SI unit of mass is the kilogram (kg).
