A 96.0 kg person stands on a scale in an elevator. What is the apparent weight in each of the following situations?
when the elevator is accelerating upward with an acceleration of 1.90 m/s^2
when the elevator is moving upward at a constant speed
when the elevator is accelerating downward with an acceleration of 1.50 m/s^2
i thought the accelerating upward problem was as simple as 1.90 m/s^2 * 90 which would give the newtons, but i don't think i'm right here.
need some help with each of these please.
Many people just shorten the phrase "acceleration due to gravity" to just "gravity." (I've caught a number of professor's doing this too!) But I warn people against it since they are calling g, an acceleration, by the name "gravity," which is a force. I have seen a number of students giving the units of g as Newtons because of this, which is (of course) incorrect.
