text: In particular, since Newton's eight definitions and three laws indicate that forces are proportional to mass and to acceleration, and since mass—or the quantity of matter, a concept Newton transformed from its Cartesian origins, where it was understood as a measure of a body's volume—and acceleration are both quantities that can be measured, Newton gives us a means of measuring forces.
text: This is because acceleration is the measure of how fast an object is increasing its speed over time.
