- 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)
- 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
- 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 Torque has units of Force*distance
- Do Joule Thiefs Work With Supercapacitors - Physics Forums
If you have the Joule thief as intermediate step all the time, you have its efficiency loss for the whole discharge - you could even end up with less energy than before If you want to use it only once the capacitor is below 1 V, you need additional logic for that I would be surprised if it helps
- 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
- 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)
- 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
