I'm having trouble with this one: How do I convert joules to newtons?(adsbygoogle = window.adsbygoogle || []).push({});

Say I have a source of energy E that is capable of supplying 10 joules -- per second -- that I wish to use to accelerate a body. Would the energy supply then look something like this(?):

E/s = 10 * 1kg * m^2 / s^2 /s

or

= 10kg * m^2 / s^3

If I divide this by m/s -- which seems to be (v)elocity -- I get(?):

E/m = 10kg * m / s^2

ie 10 newtons.

So is that the way it works in this case? Divide E/s by the *current* (non-Lorentz) velocity to get E/m as (instantaneous) newtons? If so, what happens when the velocity is (or approaches) zero? In the expression E/m, which "m" is this?

Thanks.
