An observer in free fall is weightless as he is accelerating at 9.8 m/s^2. However, when a skydiver jumps from a high plane, his acceleration gradually slows until becoming 0 m/s^2 at terminal velocity. My question is, does the constant speed of a skydiver at terminal velocity mean that the skydiver has weight?
Put it this way - If he carried a scale strapped to his back, and sitting on the scale was a 1 kg weight, at the instant after he jumps out of the airplane the scale will read 0, but when he reaches terminal velocity the scale will read 1 kg.
So, what exactly does it mean to say that he has weight?
