Increasing the distance between two objects decreases the gravitational force between them, following an inverse square relationship.

Increasing the mass of one object increases the gravitational force between it and another object proportionally.

The object accelerates until air resistance equals gravitational force, resulting in terminal velocity.

1: Mass 1 ($m_1$), 2: Mass 2 ($m_2$), 3: Force on $m_1$ due to $m_2$ ($F_{12}$), 4: Force on $m_2$ due to $m_1$ ($F_{21}$)

1: Distance (r), 2: Gravitational Force (F), 3: Earth, 4: Object

Near Earth's Surface: $g = G frac{M}{R^2}$ (R is Earth's radius, g is approximately constant) | Far from Earth's Surface: $g = G frac{M}{r^2}$ (r is distance from Earth's center, g varies with distance)
