Matchless Equation For Joules
In practical terms even a small force can do a lot of work if it is exerted over a long distance.
Equation for joules. Basically you can work out how many joules are being exerted by multiplying power by time. Work joules force newtons x distance meters where a joule is the unit of work as defined in the following paragraph. Substituting the values in the equation we get Q 10 2 300 30 60 54000000 J or 54 MJ.
Therefore the dimensional formula of Joule is the same as that of the work done. In terms of other units one Joule is equal to one kilogram meter squared per second squared. Here c is the speed of light which since its a speed is measured in meters per second.
This is the most basic formula for a joule. What is a good amount of joules for a surge protector. It has been found that J 42 joulescal 1 joule 10 7 ergs 1400 ft.
