A joule is a unit of energy equal to the work done by a force of one newton moving an object one meter. Lifting a small apple one meter up in the air expends about one joule of energy. 10 Erg Due to its small size, an erg is practical in theoretical physics for energy calculations...
It seems likely that flux directionality plays some role; in strongly unidirectional cases like White Sands, boundary expansion is clearly related to dune migration33,43, but for stationary fields of star dunes like the southeast Grand Erg Oriental23, sand supply must be the dominant factor. ...

a joule is the same thing as a newton-meter. Other units you are likely to encounter for heat include the calorie (cal), British thermal units (btu) and the erg. (Note that the "calories" you see on food nutrition labels are actually kilocalories, "kilo-" being the Greek prefix denot...

An erg measures energy or work done. It is in the centimeter-gram-second category of units. It is the work done with the force of one dyne over a distance of one centimeter. Answer and Explanation: Learn more about this topic:
The joule is also the unit of energy in the SI system, although it's customary to use ergs when measuring in centimeters and grams. 1 joule=1 kgm2/s2 \1 erg=1 gcm2/s2 Power is defined as work divided by time, so its units are joules/second. Scientists have another name for this...

ERGM will increase this to 18 MJ, and AGS will press the limits of conventional gun physics by attempting to achieve muzzle energy in excess of 33 MJ. The second revolution in military affairs We note that the choice of binary social relations is dictated by the ERGM methodological framework,...
