The plan: Video clip of the day Kepler’s equations Universal gravitational constant Universal gravitational constant examples

Newton’s Law of Universal Gravitation: Fg = force of gravity in newtons (N) m1 = first mass in kilograms (Kg) m2 = second mass in kilograms (Kg) r = distance between centers of mass in meters G = Universal Gravity Constant (***next slide for units***)

Satellites in space: A satellite in space moves around a heavy body. To keep the satellite from smashing back into the Earth (or planet it is orbiting), scientists set the force of gravity equal to the centripetal force. Fg = Fc
