You are standing on a scale in an elevator. suddenly you notice your weight decreases. what do you conclude? you are standing on a scale in an elevator. suddenly you notice your weight decreases. what do you conclude? the elevator is accelerating downwards. the elevator is accelerating upwards. the elevator is moving at a constant velocity upwards. your diet is working. the elevator is moving at a constant velocity downwards.

Imagine someone would cut the cable of the elevator. The elevator, the scale and the person inside would be in free fall and that person would be "weightless". So I would conclude the elevator is accelerating downwards.

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction
