Keeping the total mass constant 1.  Look at the data: as the net force increased, what happened to the acceleration? Did it increase, decrease or stay constant? 2.  Did a change in the net force produce a change in acceleration by the same factor? Do your results agree with Newton’s 2nd Law? 3.  Make a plot of Net Force vs. Experimental Acceleration and draw the best fitting line.
