You stand on a spring-loaded bathroom scale in a bathroom. The scale "reads" your mass. What is the scale actually measuring?
Similarly, you stand on a spring-loaded bathroom scale in an elevator that is accelerating upward at 2.0 m/s^2. The scale "reads" your mass. What is the scale measuring?
A) Your mass B) Your weight C) The force of the scale pushing up on your feet D) The force of your feet pushing down on the scale
To me, C seems correct for both of them, but B also seems correct for the first part, as weight is equal to the force of the scale on your feet for that part. Can anyone corroborate or deny my assumptions?
