bump. there are too many instances of these combinations in physics to ignore--I have to understand the reasoning behind it!

If a = constant x F
and a = constant / m

then you combine them to make

a = constant x F/m

yeah that is the part that I don't understand... could you walk thst through step by step and perhaps give an example?

I'd really appreciate thst

OK lets see if I can break it down more

a = constant X F providing that M is constant

ie we apply different forces to the same mass


a = constant / m providing that F is constant
ie we apply the same force to different masses


when we combine them into

a = constant x F/m we can get both relationships in one

when m is constant, we get the first one (combining the constants)
when F is constant we get the second one
