Lab Setup
Cart moves along track into force sensor.
Calculations
initial momentum - v*m - 0.5m/s * 0.501kg = 0.2505kg(m/s)
final momentum - v*m - (-0.4)m/s * 0.501kg = -0.2004kg(m/s)
impulse (change in momentum) : (-.2004) -0.2505 = -0.4509
impulse (area under FvT) = -0.03206
% difference : |-.03206 + .4509|/.4509 = 92%
initial momentum - v*m - 0.5m/s * 0.501kg = 0.2505kg(m/s)
final momentum - v*m - (-0.4)m/s * 0.501kg = -0.2004kg(m/s)
impulse (change in momentum) : (-.2004) -0.2505 = -0.4509
impulse (area under FvT) = -0.03206
% difference : |-.03206 + .4509|/.4509 = 92%
Uncertainties
In this lab there were many possibilities for error and uncertainty. On root of this was the ramp was not exactly flat and even on both sides. Even though we attempted to fix the problem by placing paper underneath one side this was not a complete perfect fix. Another cause could have been the sensors when they recorded and when the stopped relating to the movement of the carts. Any of these issues could have caused problems in our data.
Conclusion
Through this lab we were supposed to be able to verify the impulse equations. The impulse equation is supposed to be equal to the change in momentum as well as the area under a force time graph. Through the experiment I conducted with my group however the percent error was very great. This could be due to many problems including the uncertainties or other flukes that could have occurred. Doing this experiment it showed that they were supposed to be equal but my data was skewed and did not exemplify these findings. In order to truly verify the experiment I would need to do this experiment again and carefully measure the data and calculations.
