Universal gravitational constant examples

3. 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***)

4. 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
