[Missing term(s)] Missing g, standard gravity, or relative centrifugal force

[bvenn]

For every centrifugation step you need to know the relative centrifugal force (RCF; x * 9.81 m/s²). I couldn't find any unit that matches my expectation so I suggest to add the terms

1. rcf
2. relative centrifugal force
3. standard gravity
4. g

that could be a child term of acceleration unit.

I have added the terms g-force, relative centrifugal force and standard gravity under unit>acceleration unit. I have added g as an exact synonym for g-force and rcf as an exact synonym for relative centrifugal force for now as OBO Foundry principles state that abbreviations should not be used as term labels, but if this is not conducive to metadata annotation we can revisit.
