Physics 235 Chapter 5- 9 -F m = m r m = − GmM E r 2 ˆ r − GmM m R 2 ˆ R Figure 6. Geometry used to determine the forces on a volume of water of mass m , located on the surface of the earth. The force exerted by the moon on the center of the earth is equal to F E = M E r E = − GM m M E D 2 ˆ D When we view the motion of the water on earth, we view its motion with respect to the earth. We have used a correct inertial frame to determine the acceleration of the individual components
