The shape of an object affects it's free-fall density

AI Thread Summary
The shape of an object significantly influences its free-fall acceleration due to varying wind resistance. For instance, an egg and a Rubik's cube experience different drag forces during free fall, affecting their acceleration rates. To demonstrate this, calculations showing the differences in drag for various shapes are necessary. The discussion emphasizes the importance of quantifying these effects to support the argument. Ultimately, understanding how shape impacts free-fall dynamics is crucial for accurate physics analysis.

I'd think that they would want a bit more than this :biggrin: You'll have to show some calculations, I don't remember the equations right now (haven't done this in a long time) but you'd want to show that the drag would differ for bodies with different shapes.
 
Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
Thread 'A cylinder connected to a hanged 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...
