Given a scientific passage and an answer, generate a question for the given answer.

Passage: For a full description of weight, look at Forces: Mass versus Weight. In sum, weight is the result of the force of gravity being opposed by the normal force. As we just learned, objects in orbit are in freefall; they have nothing exerting a normal force against them and thus no weight. Answer: weight
Output:
What property is the result of the force of gravity being opposed by the normal force?
