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
I can easily picture joules per second (I just see light of varying intensities passing a point at varying rates) I don't know what a joule second is. I know that Plancks constant is just to use the frequency of the photon to find out its energy but what in the name of God is a joule second?

Torque & Joules: Fact or Fiction? - Physics Forums
Wikipedia says that the unit of magnetic dipole moments is calculated by Joule/B that means that the torque is measured by joules I really doubt that, it seems non sense.

Flash Joule Heating (FJH) Method for treating process waste streams
I caught the tail end of a video about a new application for treating chemical or process waste, which is applied to 'red' mud or contaminated bauxite residue, but the person of interest mention recovering critical minerals from consumer electronics, as well as treating mine tailings and...

What is the Definition of 1 Joule and How Does it Relate to Lifting ...
Someone told me that 1 Joule is roughly the amount of energy required to lift a 1 kilo object 10 cm of the ground. This sounds weird to me. Seems the amount of energy required would depend on how fast you lifted the object? The more time you were to spend lifting, the more energy you would spend...

What is the Definition of the Joule and How Does it Relate to Energy ...
Mentor's note: Moved from HW for a better fit Homework Statement:: A joule is defined as "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 meter." Explain this definition. Relevant Equations:: 1J = 1N.m...

Joules per Coulomb and the Volt - Physics Forums
Hey, 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...

What Is the Joule Thompson Effect and How Is It Calculated for ...
Hey all, I'm not sure this is a homework problem, more a problem I'm having with equations and this effect. Experimentally we measured dT and dp, I plotted them, then determined the Joule Thompson coefficients for 3 gases (He, CO2, N2). These values came out to be μJT(CO2) = .815 bar/K...
