Why is heat measured in joules? - Physics Forums During his honeymoon in Switzerland Joule along with Thompson, (history does not relate why Joules and Thompson happened to meet in Switzerland during Joule's honeymoon), attempted to measure the temperature difference between the top and bottom of a waterfall, history also fails to mention what Joule's bride Amellia thought of it
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
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 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 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
Why is the Velocity equal to joules per kilogram? 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
