Modelová Otázka ID 3191 - 
Pokud dva hmotné body přesuneme do vzdálenosti rovné čtyřnásobku původní vzdálenosti, dojde mezi těmito body k následující změně gravitační síly:
Správná odpověď je: D
Gravitační síla, jíž na sebe dva hmotné body působí, je dle Newtonova gravitačního zákona přímo úměrná součinu hmotností těchto hmotných bodů a nepřímo úměrná druhé mocnině vzdálenosti jejich středů. Vzroste‑li vzdálenost středů těchto hmotných bodů 4×, výsledná gravitační síla mezi těmito body klesne 16krát.
