- $F = ma$ - $F$ = [[Force]] - $m$ = [[Mass]] - $a$ = [[Acceleration]] - net force on an object is equal to the mass of the object multiplied by its acceleration - this law ties [[Force]] and [[Acceleration]] together, via [[Mass]] - the vectors point in the same direction, but [[Force]]'s magnitude is also multiplied by [[Mass]] - more specifically, equation is $\sum F = ma$ - where $\sum F$ is the net force vector
