- 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 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
- Do Joule Thiefs Work With Supercapacitors - Physics Forums
I have a supercapcitor to power some of my small projects The only problem is that the voltage drops gradually, unlike a lithium ion battery, in which the voltage is mostly stable throughout My boost converter that I am using to boost the voltage up to 5 volts, stops working with an input
- 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)?
- What is the Definition of 1 Joule and How Does it Relate to Lifting . . .
One joule is the amount of energy required to exert a force of 1N through a distance of 1 meter It doesn't matter how fast you do this The RATE at which you use this energy is power A watt is a measure of power, which is a joule sec Energy is the capacity to do work, no matter what form it is in, whether it is electrical energy, mechanical energy, chemical energy, heat, etc 5 joules of
- Adiabatic cooling vs. Joule-Thomson effect - Physics Forums
The observed cooling occurs due to Joule-Thomson effect which predicts cooling of air by isenthalpic expansion at room temperature (because air is not ideal gas and so temperature does not directly correspond to internal energy)
- How to convert cm^-1 into erg or joules - Physics Forums
I'm not sure if this is the right place for this, but I can't seem to find how to convert cm^-1 into erg or joules It's a pretty dumb question, but I can't find the answer anywhere Thanks a lot in advance!
- Can Joules Be Converted to Newtons in Energy Calculations?
As Redbelly points out, Joules are units for energy and Newtons are units of force Energy per unit time is a measure of power and would be in units of Joules sec or Newton-metres sec (Force x distance time) So power can be thought of as force x speed Dividing power by speed gives the force AM
