1. The gravitational force between two masses is unaffected by the medium between them.

2. Gravitational forces between two bodies are equal and opposite, following Newton’s third law of motion.

3. The law of gravitation applies accurately to point masses.

4. Gravitational force acts along the line joining two point masses, depending only on the distance (r) without any angular dependence, showing spherical symmetry.

5. Gravitational force is conservative, meaning work done depends only on initial and final positions.

6. The gravitational force between two bodies is not influenced by the presence of other bodies.
