1.When varying the string length, which string needed the greatest force to keep the object in circular motion? Was your prediction correct? (2 points)

2.Which weight (8 washers, 4 washers, or 2 washers) required the greater force to keep it in circular motion? Which required the least force? (2 points)

3.What is it that is exerting a force on the weights? What the name of that force? (3 points)

4.How would you describe the motion of the weight on the end of the string as you swing it at a constant rate? (2 points)

5.What do you think would happen if you decreased the speed of the string? How might this affect the force on the weights? Explain. (3 point

6.Does the force you feel as you swing the string seem to remain constant, or does it seems to pull harder at certain positions throughout its circular path? Why do you think that is? (3 points)

7.Since the string is also spinning around in a circle, does this mean it too feels a centripetal force? If so, what is exerting this force on the string? If not, why not? (3 points)
