Essay Topic Ideas on Physics: Limited Resources

AI Thread Summary
The discussion revolves around finding a suitable experimental physics essay topic related to aerodynamics, specifically for a 4000-word paper. The original poster is interested in the Magnus effect but seeks specific, quantifiable variables due to limited resources. Suggestions include investigating the aerodynamics of wind-dispersed seeds, like the sycamore, although concerns about the complexity of the math are raised. Another idea proposed is to create and study paper spinners, which could provide a simpler way to explore various aerodynamic variables. The conversation emphasizes the need for manageable yet engaging topics that allow for in-depth investigation.

hello physics forums!
it is my first time here so please excuse me for any mistakes :)

i have to write a 4000 word physics essay
and i wanted to write an experimental one, something preferably related to aerodynamics (since it is my topic of interest)
does anyone have any ideas of specific topics to investigate?
i thought of investigating the magnus effect but my teacher wants specific variables that can create clear, quantitative data and i am unsure what variables to investigate
my resources here at my high school are quite limited so i would prefer ideas that do not require too much equipment, and yet something that i can investigate deeply enough to write a 4000 word essay

thank you in advance!

How about the aerodynamics of wind dispersed seeds such as the sycamore?
 
but wouldn't the math behind such an irregularly shaped object be very difficult?
and can you be more specific by providing quantitative variables i can investigate?

thanks

I think the math will be extremely difficult but for a high school project they cannot expect too much.How about mimicking a sycamore seed action by making and investigating paper spinners.I know these are toys but there is some heavy duty physics behind them.I think if you made a few spinners and played around with them you would see for yourself that there are many variables you could investigate.Whatever you choose to do good luck with it and enjoy it.
 
ok i'll give it shot
thanks!
 
I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
