if tokamak properly implements impulse, that's a physics thing and it doesn't disrupt anything. It's an average force multiplied by the time over which that average was taken.
So if you apply an impulse of say, 5 Newton-Seconds (Newtons are a measurement of force), that's equivalent pushing for 5 seconds with a force of 1 Newton.
The upshot is that if you apply an Impulse every frame, it should be the force to be applied times the timestep for the frame.
It's the weird units (force multiplied by time) that make Impulses odd to work with.
