The direction of the force of each particle is directly towards the other particle.2rGMmF=Newtons TheoremThe net gravitational force between two spherical bodies acts just as though each body was concentrated at the center of it respective mass.Using Newtons Law of Gravitation:2rGMmF=What is the acceleration due to gravity at the surface of the earth?What is the acceleration due to gravity at a height habove the surface of the earth?Circular OrbitsGrav. Force is responsible for all orbital motions.Although F = -FMS&gt;&gt; MEbaS&lt;&lt; aEThus we assume sun is fixed.Now we study the motion of the planet orbiting the Sun.What type of motion is orbital motion?...
