relationship shows to be true when the data was graphed. The line of the graph was linear and it had a positive slope. Since the units are m/s/s/N, this also can be translated to 1 N = 1 kg m / s 2 . In this case, it shows that ma is equal to mg. It can be seen that acceleration is equal to the slope which proves that acceleration is equal to (1/mass) times the sum of forces. In the second experiment, the constant was the sum of the forces since the mass was added to the iOLab unit which changed the mass of the IOLab unit. As more washers were added to the iOLab unit, the data table showed that as mass increases then acceleration decreases. When the data was graphed, it showed a slightly curved line and it had a negative sloped line. But since mass is equal to 1/slope then I calculated 1/mass for each mass. Once 1/mass and acceleration data points were graphed then this confirmed my prediction of it being inversely proportional. The line of the graph was linear with a positive slope. This time the units of the slope was m / s 2 1 / kg which can be translated to 1 N = 1 kg m / s 2 as well. Again, this proves that acceleration is equal to (1/mass) times the sum of forces. Also, the tension on the string minus the friction force. Slope is a constant in both experiments. PHYS 1010 – page 6
