Answer:
Gravitational potential
Explanation:
The gravitational potential at a point in the gravitational field is defined as the work per unit of mass that a force must carry out to transport a body, at a constant speed, from a fixed reference location to that point.
[tex]\frac{W_{ab}}{m}=\frac{GM}{r_b}-\frac{GM}{r_a}\\\Delta V_{ab}=\frac{W_{ab}}{m}\\V=-\frac{GM}{r}[/tex]
The negative sign indicates that the work done by the gravitational force implies a decrease in gravitational potential.
