Закон Всемирного тяготения
гласит, что сила, с которой два тела притягиваются друг к другу, равна отношению произведения массы этих тел к квадрату расстояния между ними, домноженному на гравитационную постоянную
. Тела в комнате притягиваются, но с очень маленькой силой из-за своей маленькой массы. Этой силы будет недостаточно, чтобы преодолеть силу трения или даже силу сопротивления воздуха.
