The Newtonian gravitational constant, G, is one of the oldest known fundamental constants in nature, and yet it is known with the least precision of all other fundamental constants. The research group at IUPUI, in collaboration with Cal Poly Humboldt, will use multiple approaches within a singular torsion pendulum apparatus to precisely determine G. Specifically, measurements will be made using the angular acceleration feedback and time of swing methods in the same apparatus, which was carefully designed for reduced error in both techniques. We expect to obtain a measurement at the 2 ppm level using these new methods.
