Final answer:
When the elevator is moving upward, the scale will show a greater reading than your weight due to the upward force exerted by the scale. However, once the elevator reaches a constant upward velocity, the scale reading will be equal to your weight.
Step-by-step explanation:
When the elevator is moving upward, the scale will show a greater reading than your weight. This is because the scale is pushing up on you with a force greater than your weight, in order to accelerate you upward. The greater the acceleration of the elevator, the greater the scale reading will be. However, once the elevator reaches a constant upward velocity, the scale reading will be equal to your weight, as there is no longer any acceleration.
