If you're going to be pedantic, at least be correct. "Absolute zero" is basically always referring to temperature, and space is not absolute zero. You're probably thinking of zero g. And in any case, zero g isn't even pedantically correct because you're still in Earth's gravitational field, so it should really be something like zero g-forces.
"Microgravity" is the usual term for orbit - it's never quite zero, due to irregularities in the Earth's mass distribution, the tidal differential across the span of your body or the spacecraft, and also influence from the moon and sun. There are also nonzero forces other than gravity acting on the spacecraft, in atmospheric drag, radiation pressure, and thermal emission, so "free fall" isn't quite fully correct either.
