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

AI Thread Summary
To test drag force, two experiments can be designed using a tub, water, fishing line, a spring scale, fishing weights, and household objects. The first experiment should measure how speed affects drag force by dragging an object, like a washer with weights, through the water at varying speeds while recording the force on the spring scale. The second experiment can investigate the influence of texture and shape on drag force by using different household objects with varying surfaces and shapes. Neutral buoyancy may be a relevant concept to explore for accurate measurements. Clear guidance on setup and execution is essential for successful results and completing the lab report.

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 would go for neutral buoyancy.
 


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

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
