Question

What should a graph of Force vs. Mass look like to show the direct proportionality between the two? What does the slope of the line represent?

Answer 1

slope= Force/Mass

force is measured in Newtons (N) and mass in kilograms (kg). This means that the units of the slope are N/kg. However a Newton is also equal to one kg*m/s2, so if we divide this by one kg we are left with a slope with units m/s2, which acceleration is measured in!
