Question

What variables affect the gravitational force between two objects? Select all that apply
mass
distance between them
volume
air pressure
speed

Answer 1

The variables that affect the gravitational force between two objects are:

- **mass**: The gravitational force increases with the mass of the objects.
- **distance between them**: The gravitational force decreases as the distance between the two objects increases.

The other options do not affect the gravitational force:

- **volume**: Volume does not directly affect gravitational force; only mass does.
- **air pressure**: Air pressure does not have a direct effect on gravitational force.
- **speed**: The speed of the objects does not affect the gravitational force between them.

So, the correct selections are **mass** and **distance between them**.
