The three correct statements about Newton's theory of universal gravitation are:
- Gravitational force increases as the mass of objects increases.
- The theory applies to all objects in the universe.
- Gravitational force increases as the distance between objects decreases.
The statements about gravitational force increasing as the mass of objects decreases and as the distance between objects increases are false. The theory does not apply only to objects on Earth; it applies to all objects regardless of their location in the universe.
