Please someone explain, does $$F=-mg \quad \textrm{vs} \quad F=+mg$$ not matter? This is just a single term but if the EOM have multiple terms, this sign would surely make a difference. And in essence to me, it feels like it voids the negative sign in ##L=T-V##, if we can choose any sign for V. That must definitely not be the case, so where am I wrong in my reasoning?
