    Okay, so a question asked me, "which of the following equations shows you how you would solve for mass if you knew the force acting on an object, and the acceleration?"

    The answer was m = f/a.
    How is this so?

    Thanks in advance.

    Newtons second law is typically stated as . Take magnitudes and solve for m

    As is often the case with technical subjects we are presented with an unfortunate choice: an explanation that is accurate but incomprehensible, or comprehensible but wrong.
