Free falling bodies:
Correct answer: C. Have no weight
- A. Have maximum weight
- B. Have minimum weight
- C. Have no weight
- D. Have any weight
Explanation
The correct option is: C) Have no weight When a body is in free fall, it accelerates under the influence of gravity, and during this period of free fall, it experiences weightlessness. Weight is the force with which gravity pulls an object toward the center of the Earth (or any other massive body). In free fall, the object is essentially in a state of continuous acceleration, and it is not resisting gravity. As a result, the normal force (which gives the sensation of weight) experienced by the object is zero, and it is effectively 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.
