Morning all, I have a need to write a lot of physical quantities - these should be in text mode. Mostly I can manage, but subscripts are causing me grief
Eg \startformula \startmathalignment[n=3] \NC \text{F}\NC =\NC {\text{GMm} \over \text r^2}\NR \NC \text {force}_G \NC =\NC {\text{G} \times \text m_1 \times \text m_2 \over \text r^2}\NR \NC \text {force \low G} \NC =\NC {\text{G} \times \text m_1 \times \text m_2 \over \text r^2}\NR \stopmathalignment \stopformula
In the second and third equantions I'd like force subscript G all in roman, not italic, to follow the standard conventin. The first one puts the G in the correct place, but in italic The second one manages roman, but it's offset.
Is this ok? \text{force}_{\rm G} (or \text{force}_{\text{G}}) With \rm you stay in math mode, but use roman. You should not use \rm for "force" since you would get mathematical spacing instead of proper kerning.
\startformula {\forceQA \over \massQA} = \accelerationQA \stopformula
Try to use \frac{}{} instead of \over. There are discussions about disabling \over in luatex (or at least in MKIV). Mojca
