5.3Gravitational Force proportional to mass

The gravitational force of an object is mathematically proportional to its mass.  We know that F = MA.  In the case of gravitational forces, we use the same equation.  Specifically the equation would follow this logic.  Gravitational Force (also known as weight) = The mass of the object multiplied by the acceleration due to the gravitational field strength.  In a simplified equation dealing with an object on earth, it would simply be expressed as Weight= mass x gravitational acceleration (10m/s/s).  In summary, on earth, if you multiply the mass of an object
