| - | Newton's law of Gravity tells us that the $\color{blue}{\text{gravitational force}}$ between $\color{red}{\text{two}}$ $\color{orange}{\text{masses}}$ gets smalles as the masses are removed $\color{magenta}{\text{farer away from each other}}$. | + | Newton's law of Gravity tells us that the $\color{blue}{\text{gravitational force}}$ between $\color{red}{\text{two}}$ $\color{orange}{\text{masses}}$ gets smaller as the masses are removed $\color{magenta}{\text{further away from each other}}$. |
| In addition, it tells us that the //exact// strength of the $\color{blue}{\text{gravitational force}}$ is determined by the $\color{olive}{\text{gravitational constant}},$ the $\color{red}{\text{two}}$ $\color{orange}{\text{masses}}$ of the objects in the system and the $\color{magenta}{\text{distance between them}}$. | In addition, it tells us that the //exact// strength of the $\color{blue}{\text{gravitational force}}$ is determined by the $\color{olive}{\text{gravitational constant}},$ the $\color{red}{\text{two}}$ $\color{orange}{\text{masses}}$ of the objects in the system and the $\color{magenta}{\text{distance between them}}$. | ||
