% uncertainty = uncertainty * 100 / slope =
0.01944802* 100 /1.0195= 1.907686 %
Error Analysis:
Our slope of Impulse versus Change in Momentum gives us a slope of 1.0195, which is
close to the expected value of 1. A slope of 1.0195 is actually acceptable because the
accepted value is 1 and falls within one standard deviation of the experimental slope
value. Our experimental value had a percent uncertainty of 1.907686%, which is
acceptable, and preferred. This experiment would probably be repeated without
