Title: Testing Hydrodynamics
Problem Statement: How does the shape of an object affect its drag and Hydrodynamics?
Hypothesis: These are our predictions for time in seconds for each weight to travel through
the tube. We made this hypothesis by testing weight 1 and predicting the others through the
time we got. Basically, we believe that weight 3 will have the least drag, weight 1 the second
least, and weight 3 the most.
Method and Materials: See Method and Materials Page
Results: See Results Page
Conclusion: We discovered that Weight 2 had the least drag, Weight 1 the second least, and Weight 3 the most drag. From those results we went on to suggest that the shape of the back of the weight also affects the drag. Even though Weight 1 had a smaller frontal surface area, Weight 2 had less drag.
