We played our final round of Who's Who. I also checked the homework, which was to finish graphing the data from the Force-Mass Lab. We reviewed how to calculate slope, then we used Graphical Analysis to graph our data and generate a line of best fit. 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.
