... Mass • m • kg • The quantity of matter in a body; the measure of a body’s resistance to acceleration. Quantity of inertia. NOT the same thing as weight (which is gravitational force). Force • F • N or kg·m/s2 • A measure of the push or pull involved when two bodies interact. Sometimes expressed as a ...
