Take the 500 g mass (or another mass that you have been provided) and attach it to the end of the spring scale. Because the spring scales may not be totally accurate, record the reading on the scale in the space below. 2. Draw a Free Body Diagram for the mass and spring scale system while it is at rest in the space below. Include the "Force of the Scale" and "Weight of the Mass". Indicate the relationship between these two forces. Figure 2.2: Moving Scale 3. Before we proceed any farther, let's do a quick thought experiment. What would happen to the reading of the scale if you were to move the scale up or down with a constant velocity, while the mass was attached (but without touching the mass)? Would the reading on the scale increase, decrease, or stay the same? Briefly explain your reasoning. 4. Now, with the 500 g mass attached, hold the scale and move it up and then down with a constant velocity. What happens to the reading of the scale as you do so? Was your group's hypothesis correct? If not, explain why. 5. Draw a Free Body Diagram for the mass and
