Aman standing on a scale in an elevator notices that the scale reads 30 newtons greater than his normal weight. which type of movement of the elevator could cause this greater-than-normal reading? explain.

An upwards acceleration of the elevator would cause this greater reading since the scale displays the Normal Force of the object on it. The inertia of the person would prefer to stay stationary, so the scale must push up on the person to accelerate him upward along with the elevator. This results in the following equation:

W = mg + ma

Where mg represents the weight reading without external acceleration and ma as the weight reading due to the external acceleration.
