Gravity depends on two key qualities of objects: their mass and the distance between them.

Quick Scoop

Short answer

  • The gravitational force between two objects increases as their mass increases.
  • The gravitational force between two objects decreases as the distance between them increases.

In equation form, Newton’s law of universal gravitation is often written as F=Gm1m2r2F=G\frac{m_1m_2}{r^2}F=Gr2m1​m2​​, which shows that gravity depends on the masses m1m_1m1​ and m2m_2m2​, and the distance rrr between their centers.

So, when someone asks “what two qualities of objects does gravity depend on?”, the answer is: mass and distance.

TL;DR: Gravity gets stronger with more mass and weaker with more distance.
