SUMMATIVE: Newton's II Law Lab

We've made it to Newton's 2nd Law, which describes the relationship between three variables: Mass, Acceleration, and Force.

This lab will be half your grade for our forces unit, averaged with our end of unit test. In groups of 4, develop an experiment that measures and determines the relationship between Acceleration vs. Force (hint, your primary deliverable should be an Acceleration vs. Force graph). 

Your report should include the typical components of a lab. You can use this template Links to an external site. and example to aid you.
Title - Name of study/lab, with group members names
Abstract - What is the point of this lab? What variables are we investigating? What is a one sentence description of the results?
Methods - What is the set up? What procedure did you use to collect data and measure variables? Describe tools, equipment and process. 
Results (graph!!) - Include your beautiful, properly labeled and scaled graphs. Acceleration v Force, and Acceleration v Mass. These should be included based on our first unit about modeling practices. Check your notes or look in the modeling and science practice module. 
Analysis - What is the relationship between acceleration and force? How do we represent that with a math model? What does the slope represent in the graph? What is the vertical intercept, and if significant, what does it represent? (5% rule can be used to discard a small but non-zero intercept value). Complete a percent-error calculation for slope/coefficient. % error = (experimental value - theoretical value)/theoretical value x 100.
For exceeding, this should be done for acceleration vs mass as well. Hint: What are the units for your slope/coefficient? 
Conclusion - Based on your math models, what is the general form equation linking Force, acceleration and mass? AKA Does your data support Newton's II law: Fnet (N) = mass (kg)*acceleration(m/s^2)

Acceleration vs System Mass data for analysis:

Mr. Fenbert's Data. Cart and Sensor mass was 0.684 kg. 1/system mass = 1.46 1/kg
