Question

17. Suppose you were standing on a scale in an elevator in free fall. What would the scale read?

18. Explain why the feeling weightlessness in free fall is not the same as truly being weightless.
19. In what ways are roller coaster rides similar to and different from training simulations in a NASA plane?

Answer 1

17

What would the scale read? zero

18 In free fall you are being pulled by a gravity. "Truly" weightless presumably happens in deep space where there is nothing to pull you.

19 coasters accelerate down to simulate weight loss/zeroised. As do NASA planes,

Roller coasters are for fun seekers. NASA is for science
