G ME 1. Slides 33 - 35 of the PowerPoint describes Newton's Law of Universal Gravitation: mm2 Fg r2 where G = 6.67 * 10-11 Nm2/kg' is the universal gravitational constant. Considering that on Earth you are subject to the acceleration of gravity g = 9.81 m/s?, and Fg = mg, where m is your mass in kg, g=G RE' where Me and R are the mass and radius of the Earth, respectively
