Question

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

a. Moves upward with increasing speed.
b. Moves downward with increasing speed.
c. Moves upward with constant velocity.
d. Moves downward with constant velocity.

Answer 1

The scale shows the highest reading when the elevator moves upward with increasing speed.

Step-by-step explanation:

The scale shows the highest reading when the elevator is moving upward with increasing speed. When the elevator accelerates upward, the scale pushes up on the person with a force greater than their weight. The greater the acceleration of the elevator, the greater the scale reading.
