The joule (symbol: J) is the basicSI unitofenergy. A joule is equal to thekinetic energyof a kilogrammassmovingat the speedof one meter per second (one joule is a kg⋅m2⋅s−2). Alternatively, it is the amount of work done on an object when a force of onenewtonacts in the ...

(Units) the derived SI unit of work or energy; the work done when the point of application of a force of 1 newton is displaced through a distance of 1 metre in the direction of the force. 1 joule is equivalent to 1 watt-second, 107ergs, 0.2390 calories, or 0.738 foot-pound. Symbol...
The meaning of KILOJOULE is 1000 joules; also : a unit in nutrition equivalent to 0.239 calorie.
In the International System of Units (SI), energy is measured in joules. One joule is equal to the work done by a one-newton force acting over a one-metre distance. Energy is treated in a number of articles. For the development of the concept of energy and the principle of energy cons...
11. Abbr. w Physics The transfer of energy from one physical system to another, especially the application of a force to move a body in a certain direction. It is calculated as the product of the force and the distance over which it is applied and is expressed in joules, ergs, and foo...
The most familiar fluid is of coursewater, and an encyclopaedia of the 19th century probably would have dealt with the subject under the separate headings ofhydrostatics, the science of water at rest, and hydrodynamics, the science of water inmotion.Archimedesfounded hydrostatics in about 250bcwh...
q is the heat transferred per second in Joules. {eq}\Delta T {/eq} is the difference in temperature in degrees Celsius or Kelvin between the two substances The coefficient of convection is a property of the substance being heated and will vary for different substances. ...
