Newton to Joule ?

  1. Nov 17, 2011 #1
    I want to know how Newton can be converted to energy (Joule).
    At least approximately...

    For example let's say a crankshaft transfer a force, - exactly 100000 Newton

    How much energy would be transferred be per second, - included all what is "lost" to heat etc..

    You can't convert Newtons to Joules, just like you can't convert meters to seconds. They are different units.

    a Newton is a unit of FORCE.
    A joule is a unit of ENERGY
    Energy = force x distance moved by the force

    not sure if this is obvious or not...but for your example with the crankshaft: if it has a force of 100,000 N and you move it a distance of 2 meters, you have done work. work is equal to energy. That, my friend, is how you relate joules to newtons.
