- What really is a Pascal and a Joule? - Physics Forums
The same with Joule's Don't think of it as Kg*m^2 s^2, think about it as a force being applied over a distance Joule is energy, and an external force does work on an object by an amount of ##W=F\cdot ds## where F is the force and ds is a small chunk of the path that it travels (a line is 1d)
- What is a Joule Second? - Explained Easily! - Physics Forums
A joule in mechanical work is 1 N of force applied on an object to move it a distance of 1 m So a joule persecond is doing the above action in one second Btw, a "joule per second" and a "joule second" are not the same thing Jule per second is dividing by seconds, joule second would be multiplying by seconds
- Joules per Coulomb and the Volt - Physics Forums
A coulomb is the amount of charge that passes a point through a wire carrying one ampere for one second Voltage is a measure of electrical potential energy in units of volts or joules per coulomb (energy charge) Then 1 volt means 1 joule per coulomb; 2 volts mean 2 joules per coulomb, and 5 volts mean 5 joules per coulomb
- What is the Definition of 1 Joule and How Does it Relate to Lifting . . .
Two equivalent definitions of the "Joule" are "the work done by a 1 Newton force in moving an object 1 meter" and "the kinetic energy of a 1 kg object moving at 1 meter per second" Since a Newton is defined as "the force necessary to accelerate a 1 kg object at 1 meter per second per second", it has basic units of kg m s 2 and so, multiplying

- Adiabatic cooling vs. Joule-Thomson effect - Physics Forums
For helium however, Joule-Thomson inversion temperature is far below room temperature, therefore, when deflated, a helium-filled tire will warm up instead A's rebuttal : B is wrong Free expansion (as in Joule expansion experiment) assumes expanding against vacuum , and only predicts that temperature of (ideal) gas will be the same after the
- Why 1 liter * atm = 101. 33 joules - Physics Forums
Are you asking why it comes out equal to 101 33 Joules, or why a pressure (atm) time a volume (liter) gives an energy (joules)?
- How to convert cm^-1 into erg or joules - Physics Forums
You cant, because cm^(-1) is not a unit of energy The base units of energy are m l t^(-2) For example Ergs are grams cm seconds^(-2) and Joules are kg m seconds^(-2)
