... • If the elevator has a downward acceleration, then n – w = m(– a). So, n= m(g – a). • If the elevator cable breaks, then a = g, and so n = 0, Hence, the person (and everything else in the elevator) has an apparent weight of zero. This is apparent weightlessness. This is what astronauts in orbit (or ...

... in the absence of external forces! In the first two sample problems, we dealt with a frictionless surface. We couldn’t simply conserve momentum if friction had been present because, as the proof on the last slide shows, there would be another force (friction) in addition to the contact forces. Frict ...
