The three correct statements about Newton's theory of universal gravitation are:
- Gravitational force increases as the distance between objects decreases.
- The theory applies to all objects in the universe.
- Gravitational force increases as the mass of objects increases.
The first statement correctly describes the inverse relationship between gravitational force and distance; as distance decreases, gravitational force increases. The second statement highlights the universal applicability of the theory. The third statement indicates that greater mass leads to a stronger gravitational force.
The other statements provided are false.
