Question

18 a person experiencing free fall feels weightless because they dont have any support force on them. but they are not really weightless. a false b true

Explanation:

When a person is in free - fall, the only force acting on them is gravity. The sensation of weight comes from the normal (support) force. Since there is no support force during free - fall, they feel weightless. But their mass \(m\) and the gravitational acceleration \(g\) still exist, and their weight \(W = mg\) (where \(W\) is weight, \(m\) is mass, and \(g\) is gravitational acceleration) is non - zero. So, they are not really weightless in the sense that the gravitational force still acts on them.

Answer:

B. True
