Support of Hypothesis
How does the shape (sphere, rectangle, cylinder) of an object affect drag in water ? (I will walk the distance of the five steps with objects in the water)
I think the the square will have the most drag because of it shape the edges will help in the action of pulling it back. i predict that the spheres will not have a lot of drag beuces it round and it does do it have a lot straight to pull itself back.
Materials & Equipment
The data does not supports the hypothesis because the tea was the one with the edges but it did not have as much drag as the coffee mug which is round so my hypothesis was incorrect.
collect objects,measure and cut fishing line,tie fishing line to the object,put the spring scale on the other end of the fishing line,go to the pool, but don’t get in,walk across the edge of the pool,keep the object in the water, do not let it touch the bottom,take 5 slow steps (be specific with distance),measure the drag on the spring scale,repeat with each object
pool,scissors fishing line ,spring scale several spheres (how much and what sizes, weight) several cylinders,several rectangles
