Question: (a) An object is placed on a spring scale in an elevator moving upward at a constant speed. Is the reading of the scale greater

(a) An object is placed on a spring scale in an elevator moving upward at a constant speed. Is the reading of the scale greater than, smaller than, or the same as the reading obtained in a stationary elevator?

(b) How does the reading of a scale in an elevator that has upward acceleration $a=0.5 \mathrm{~g}$ compare with the reading obtained in a stationary elevator?

(c) What if the elevator has downward acceleration $a=g$ ?
