A2_8 A Girl and her Horse

Mac McMullan, Tom Filip, Megan Perks, Natalia Stylianou


Horse-girls and their horses are inseparable in real life, but how strong is the actual gravitational bond between them? Using Newtonian gravity, we investigate by approximating both girl and horse as cylinders, and find they have a gravitational force between them of 4.9 x 10^(-6) N. We also investigate the size of the force exerted between the girl and the horse in free space if they were 100 m apart, and find that it would take them 194 days to drift back together under the influence of their own gravity alone.
