The slope A of your best fit line on the force vs acceleration graph should be equal to the mass of the cart and probe (in kg), if force and acceleration truly are proportional. How does the slope value compare with the mass value?

Answer #1
slope = y/x = F/a
By Newton's second law, F= ma
So, m = F/a, which is nothing but the slope
So, slope = mass.

Answer #2

slope = y/x = F/a
By Newton's second law, F= ma
So, m = F/a, which is nothing but the slope
So, slope = mass.
