PLEASE ANSWER BY TONIGHT!: What is an experiment to test drag force...?

...using only a tub about 14inx10inx7in, water, fishing line, a spring scale, fishing weights, and random household objects?

we're suppose to design two experiments: one to test the effect of speed on drag force, and one to test if texture/shape influence drag force.

we also have to write a formal lab report on it, so if you have any tips, share the knowledge!

and please help! this is my test over this chapter, and i am clueless!

Given the items at your disposal, how can you measure force? Force on what (a specific household object)? What material do you want to use as the dragging medium?

The best suggestion that I can give: play around with stuff.
 


well, i mean... i tried using a simple washer, tying the fishing weights to it, and dragging it thru the tub to get a reading on my spring scale. nothing works, and no one in my class knows what to do either. and this is due by friday and we only get tomorrow to work on it in class.
 


i have no idea what that is. i need some ideas on how to set this up to obtain results.
