ConclusionBoth of these experiments proved Newton's Second Law. Newtons second law is Net force=mass*acceleration or acceleration=net force/mass. In the acceleration vs mass graph the 270/mass in grams is because the net force is 270 g*m/s/s. This proves that acceleration=net force/mass. In the first experiment, the linear relationship between acceleration and net force proves that Net force=mass*acceleration. One improvement to this experiment could be to make the ramp bigger so more data could be collected to limit the uncertainty of our experiments.

Evaluating ProceduresThe main source of uncertainty for the both experiments was that we often forgot to stop the cart or we stopped it at different times each time so we didn't get the same amount of data for each trial. Another source of uncertainty for both experiments was that it was hard to figure out which part of the data from the velocity-time graphs was the correct data because there was almost always a big spike or drop in the data. The data from the second experiment has far more uncertainty which is most likely just because of these two reasons, but its data was affected more than the first experiment.
