For the Results Section of the Report:
Create a plot of Theoretical Force vs. Momentum (the grid above is for a sketch). Draw a best fit line through
the points. You can plot all plate types on one graph.
For the Conclusion of Report:
What is the relationship between Force and Momentum?
Explain the term (1- cosβ). What does it tell you about the magnitude of force being deflected?
What is the percent error of the measured force to the theoretical force? Be sure to explain sources of error is
necessary.
