Jak se změní gravitační síla působící mezi dvěma tělesy, jestliže dojde k trojnásobnému nárůstu vzdálenosti těchto dvou těles?
Správná odpověď je: C
Velikost gravitační síly dle Newtonova gravitačního zákona závisí přímo úměrně na součinu hmotností obou na sebe působících těles a nepřímo úměrně na druhé mocnině vzdálenosti jejich těžišť. Jestliže tedy vzdálenost těžišť těchto těles vzroste na trojnásobek, gravitační síla se úměrně tomu 9× sníží.
