Gravitational force can be considered as a:
Correct answer: B. Universal force
- A. Fictitious force
- B. Universal force
- C. Pair of action and reaction forces
- D. Dragging force
Explanation
Gravitational force is a fundamental force of nature that acts universally between all objects with mass. It is described by Sir Isaac Newton's law of universal gravitation, which states that every point mass attracts every other point mass in the universe 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.

About Gravitation
Newton’s law of universal gravitation relates the force between masses to their masses and separation, while gravitational field strength explains weight and orbital motion. The topic covers satellite velocity and period, escape ideas, weightlessness in free fall, and artificial gravity, which differs from ordinary gravitational attraction.
