Yer gonna make me use more than one word? -_-
Ughhhhh fine lolol

Force `varies directly` with Acceleration.
So force is the same as acceleration,
\(\Large\rm F=a\)
But we have to put another letter in there, we call it a `constant of variation`.
\(\Large\rm F=ka\)
zepdrix (zepdrix):
They tell us that when \(\Large\rm F=32\), that our \(\Large\rm a=8\)
OpenStudy (kidrah69):
k=4
OpenStudy (kidrah69):
?
zepdrix (zepdrix):
\[\Large\rm F=ka\]\[\Large\rm 32=k\cdot8\]\[\Large\rm k=4\]Ok good! We'll plug that back into the original equation.

So anyway...
OpenStudy (kidrah69):
nvm ._.
zepdrix (zepdrix):
We have our equation with the k value figured out.
Now they give us a NEW force value. \(\Large\rm F=12\)
We'll plug it in,\[\Large\rm F=4a\]\[\Large\rm 12=4a\]
zepdrix (zepdrix):
And try to figure out what acceleration corresponds to a force of F=12.
zepdrix (zepdrix):
What's your a value here?

So we are looking for the a value right? would it be 3?
zepdrix (zepdrix):
Yay! a=3.
zepdrix (zepdrix):
These types of problems are two steps, err really three steps I guess.
`Setting up the problem correctly`
`Using the first set of information to figure out k`
`Using the second set of information to figure out a or F`

:/
OpenStudy (kidrah69):
ok...thanks :)
