The minimum velocity required to go out from Earth's gravitational pull is called:
Correct answer: D. Escape velocity
- A. Terminal velocity
- B. Angular velocity
- C. Drift velocity
- D. Escape velocity
Explanation
Escape velocity is the minimum velocity required to go out from Earth's gravitational pull. Hence D is correct.

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.
