Question

Solve for a in terms of F and m: F=ma

Answer 1

To solve for a, you must get a by itself on one side of the equation.  Now, a is "joined" to m by multiplication.  To "separate" them, use the inverse operation, division.

Divide both sides of the equation by m.

$F=ma \\ \frac{F}{m}=\frac{ma}{m} \\ \frac{F}{m}=a \\ a=\frac{F}{m}$
