Yes. All torques or forces are in units of "blah" and get multiplied by 
the time step. So, if you assume SI units, forces are in newtons, and 
get turned into newtons-per-second impulses by multiplying by time step. 
If you want the object to stop in the duration of one time step, divide 
by the time step size.
