The three correct statements about Newton's theory of universal gravitation are:
- The theory applies to all objects in the universe.
- Gravitational force increases as the distance between objects decreases.
- Gravitational force increases as the mass of objects increases.
These statements reflect the fundamental principles of Newton's law of universal gravitation, which states that every mass attracts every other mass with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
