- If something causes something else then that something else depends on that something
- The mass of an object causes the gravitational force exerted by that object
- So, the gravitational force on an object depends on the mass of the object

Therefore, the gravitational force on an object depends on the mass of the object
Q: The gravitational force exerted by an object depends on its
Context:
