中文百科

焦耳

焦耳(简称)是国际单位制中能量、功或热量的导出单位,符号为J。在古典力学里,1焦耳等于施加1牛顿作用力经过1公尺距离所需的能量(或做的机械功)。在电磁学里,1焦耳等于将1安培电流通过1欧姆电阻1秒时间所需的能量。焦耳是因纪念物理学家詹姆斯·焦耳而命名。

以其它单位表示,

\rm 1\ J = 1\ N \cdot m = \left ( \frac{kg \cdot m}{s^2} \right ) \cdot m = \frac{kg \cdot m^2}{s^2}=Pa \cdot m^3= 1\ W \cdot s\,\!

1焦耳也可以定义为

  • 移动1库仑电荷通过1伏特电压差所需做的功,或1库仑·伏特。这关系也可以逆反过来定义伏特。
  • 产生1瓦特功率1秒时间所需做的功,或1瓦特·秒。这关系也可以逆反过来定义瓦特。
英语百科

Joule 焦耳

The joule (/ˈl/), symbol J, is a derived unit of energy in the International System of Units. It is equal to the energy transferred (or work done) to an object when a force of one newton acts on that object in the direction of its motion through a distance of one metre (1 newton metre or N·m). It is also the energy dissipated as heat when an electric current of one ampere passes through a resistance of one ohm for one second. It is named after the English physicist James Prescott Joule (1818–1889).
