The force of gravity between two objects increases.
According to Newton's law of gravitation, the gravitational force is given by the formula:
\[ F = G \frac{{m_1 m_2}}{{r^2}} \]
where \( F \) is the gravitational force, \( G \) is the gravitational constant, \( m_1 \) and \( m_2 \) are the masses of the two objects, and \( r \) is the distance between their centers.
As the distance \( r \) decreases, the value of \( r^2 \) also decreases, leading to an increase in the gravitational force \( F \).
