Gravitational potential

The gravitational potential ($$\Phi$$ or $$V$$) is the gravitational potential energy per unit mass.

$$\Phi$$ at a point is defined as the work done by a gravitational field on a unit mass in bringing the mass from infinity to the point in question. The potential is measured in $$\text{ J}\text{ kg}^{-1}$$ or $$\text{ kg m}^2\text{ s}^{-2}$$.

The equation for the gravitational potential is: $$$ \Phi=V = \frac{U}{m} = -\frac{GM}{r} $$$

$$r=$$distance from mass $$M$$; $$G=$$universal gravitational constant.
