The joule (/ dʒ uː l / JOOL, or / dʒ aʊ l / JOWL; symbol: J) is the unit of energy in the International System of Units (SI). [1] In terms of SI base units, one joule corresponds to one kilogram-square metre per square second (1 J = 1 kg⋅m 2 ⋅s −2).

What is Joule? Joule, a sister journal to Cell, is a home for outstanding and insightful research, analysis and ideas addressing a key global challenge: the need for more sustainable energy. Joule is a distinctive and forward-looking journal, bridging disciplines and scales of …

焦耳以英国物理学家詹姆斯·普雷斯科特·焦耳（James Prescott Joule，1818~1889）的名字命名。 焦耳最先发现了焦耳定律（Joule’s laws），焦耳定律给出了电能向热能转化的定量关系。

2019年5月22日 · Joule (unit: J). Joule is a derived unit of energy. It is equal to the energy transferred 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.

2024年8月7日 · What is a Joule? A Joule is a unit of energy in the International System of Units (SI). It is defined as the amount of work done when a force of one newton is applied over a distance of one meter. In simpler terms, a Joule represents the energy required to perform a specific action, such as lifting a small apple one meter up in the air.

A Joule (J) (/ ˈdʒaʊl / or sometimes / ˈdʒuːl /) is a unit in the SI system named after English physicist James Prescott Joule. Work done by pushing a block horizontally, with S being the displacement measured in m. Work done by lifting a block against gravity. The work done in this case equals the gain in potential energy of the block.

2019年3月7日 · The joule (symbol: J) is the basic SI unit of energy. A joule is equal to the kinetic energy of a kilogram mass moving at the speed of one meter per second (one joule is a kg⋅m 2 ⋅s −2 ). Alternatively, it is the amount of work done on an object when a force of one newton acts in the direction of the object's motion over a distance of one ...

2023年11月17日 · Joule (J) is the standard unit of measurement for energy in the International System of Units (SI). It is defined as the energy required to move an object one meter in the direction of the force of one Newton. The joule is used in different fields, including physics, engineering, and chemistry.

The joule is the unit of energy in the International System of Units (SI). It is equal to the amount of work done when a force of 1 newton (N) displaces a ma...

The joule (Template:PronEng or Template:IPA) (symbol: J) is the SI unit of energy. It was named after James Prescott Joule for his work on the relationship between heat, electricity and mechanical work.
