    Isaac Newton called mass the quantity of matter. Mass can also be thought of as a numerical measure of inertia, that exists in the absence of gravity. Weight is the pull of gravity on a mass, and depends both on the mass and on the amount of gravitational force present.

    Equation for Weight:

    \[W = mg \nonumber \]
