Question

Do mass and acceleration have a direct or indirect relationship?

Answer 1

Hmm, let's ask Newton!
\[\huge F=ma\]\[\huge a=F \frac{ 1 }{ m } \rightarrow m=F \frac{ 1 }{ a }\]

Answer 2

It would be an indirect relationship right? Just because the two can affect each other doesn't mean they are dependent.
