We generated a scatter plot of our data from the force-mass lab and drew a line of best fit. From this we reviewed how to calculate slope, and compared our hand generated graph with the one produced last time by Graphical Analysis. Each group reported their slope values and we analyzed the group data for outliers.
Once all outliers were eliminated we learned that the slope of the line represents the Gravitational Field Strength of Earth and from this we can make a Mathematical Model. We learned how to make a mathematical model and finished our discussion of the lab with our general model that allows us to predict the force Earth exerts on every object if given the mass.
If you missed the class the discussion of making the model as well as making the general model is shown below.
Students had about 20 minutes to work on the homework.
