Finally, consider the gravitational force generated by a spherically symmetrical massive object. the magnitude and direction of such a force are given by newton's law of gravity:
$\hat{f}_{g}=-\frac{g_{m1m2}}{r ^{2}}\hat{r}$ , where ds =drr^; g, m₁, and m₂ are constants; and r> 0.
find $u_{rf}-u_{r0}=-\int_{r0}^{rf}\ vec{f}_{g}*d\vec{s}$ .
express your answer in terms of g, m₁, m₂, r₀, and $r_f$ .
