Bicycle Spinning Wheel

AI Thread Summary

A spinning bicycle wheel possesses kinetic energy while in motion, which is conserved as long as no external forces act on it. However, the wheel as a whole does not have net momentum; instead, its individual components exhibit angular momentum. This distinction arises because the wheel's rotation does not contribute to linear momentum. The conservation of kinetic energy applies to the entire system, while angular momentum is specific to the wheel's parts. Overall, the wheel demonstrates kinetic energy conservation but lacks net momentum.

2 questions.
1.when you're spinning wheel by its shaft, does the wheel have any kinetic energy while it's spinning?is it conserved?explain why.

2.does the wheel have any net momentum while it's spinning? is it conserved?explain why

1) yes, the wheel has kinetic energy

2) the entirety of the wheel has no net momentum. However, its parts all have angular momentum.

Thread 'Errors and significant figures'

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...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:
