Freely falling bodies are in a state of:
Correct answer: D. Weightlessness
- A. Rest
- B. Static equilibrium
- C. Dynamic equilibrium
- D. Weightlessness
Explanation
Dis correct. Freely falling bodies are already accelerating at a 9.81 m/s2 so experience no additional force by Earth and hence feel weightless.

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.
