You stand on a spring scale on the floor of an elevator. Of the following, the scale shows the highest reading when the elevator:

Explanation

The correct answer is that the scale shows the highest reading when the elevator moves upward with increasing speed. This is because the elevator's upward acceleration adds to the gravitational force, increasing the normal force exerted on the scale. In physics terms, the apparent weight is the sum of the gravitational force (mg) and the force due to acceleration (ma), resulting in a higher reading on the scale.In contrast, moving upward with decreasing speed indicates downward acceleration, reducing the normal force. Remaining stationary results in no additional forces beyond gravity, reflecting your true weight. Moving downward with increasing speed causes downward acceleration, further decreasing the normal force and the scale reading.
