Title Newton's Gravitational Constant Calculation
Description Student calculate the value of G using a modeling approach. They vary the M1, M2, and R in the on-line PhET app, gathering 6-10 sets of values. Then they set up a variable "X" = M1*M2/R^2 and see how it varies with the app's given value of Force. The relationship should be linear, with the slope of G and a Y-intercept very close to zero.
