What is a Joule Second? - Explained Easily! - Physics Forums
2010年7月9日 · A Joule Second, also known as a Joule-Second or a Joule Second (J·s), is a unit of energy used in physics. It is a combination of the units Joule (J) for energy and second (s) for time. It is defined as the amount of energy transferred or expended in one second by a current of one ampere through a resistance of one ohm.
What really is a Pascal and a Joule? - Physics Forums
2015年1月21日 · A joule is a unit of energy, named after the English physicist James Prescott Joule. It is defined as 1 newton-meter (N*m), which means it is the amount of work done when a force of 1 newton is applied over a distance of 1 meter.

Efficiency of an engine performing the Joule ideal-gas cycle.
2008年9月13日 · The Joule ideal-gas cycle is a theoretical thermodynamic cycle that describes the operation of an ideal gas engine. It consists of four processes: isentropic compression, isobaric heat addition, isentropic expansion, and isobaric heat rejection. How is the efficiency of an engine performing the Joule ideal-gas cycle calculated?
Why is the Velocity equal to joules per kilogram? - Physics Forums
2017年2月9日 · Because if the solution for understanding the KE Joule is by integration of Momentum. It seems like there is no connection between the formula for kinetic energy and a joule except for the units and the word joule. and that there would be a conversion of 1/2. of some sort. which only makes sense if they are not the same joule. What is a Joule.
