Actually, it has posed more questions for me now...lol. Would a human body experience any problems if accelerating in a vacuum? I assume not now, because there is no outside friction, and so there'd be no internal force...?

Thank you. That has cleared it up.

If you hit a hard surface, wouldn't you be accelerating (well, decelerating)? I need to compare only velocity where acceleration is 0 or the net force is 0. However even when the net force is 0 (as in terminal velocity), wouldn't the human body still sustain injuries? Not on Earth because...

Hi all I'm writing a paper on the relation of safety to acceleration and velocity. The actual topic of the essay is that only acceleration is related to safety, however I disagree, as unless in a vacuum, the forces of friction of external gases and fluids would affect the human body at high...
