which pair of factors affects the force of gravity between objects?\no direction and distance\no mass and…

Brief Explanations:

The force of gravity between two objects is determined by Newton's law of universal gravitation, which states that the gravitational force (F = G\frac{m_1m_2}{r^2}), where (m_1) and (m_2) are the masses of the two objects and (r) is the distance between their centers - of - mass. So mass and distance are the key factors.

Answer:

mass and distance
