Sure, if we were in space where gravity didn't exist [edit: practically isn't present], then Newton's law would be relevant here. But since we don't...

Calculations of hp won't work in space where gravity doesn't exist, since that variable is already worked into the original unit. Using this measurement in space to show 550lb 1ft/sec/sec acceleration doesn't compute correctly. HP is a unit that takes more into consideration than oversimplified newtonian physics.
