    Inertia Momentum
AI Thread Summary
A coasting rotating system slows down when a slice of bread is added due to the increase in mass, which raises the moment of inertia. This change in moment of inertia results in a greater resistance to angular acceleration, causing the system to decelerate. The discussion highlights the relationship between mass, moment of inertia, and rotational motion. Participants seek to clarify the relevant physics equations that govern this behavior. Understanding these principles is essential for grasping the dynamics of rotating systems.

Why does a coasting rotating system slows down when a slice of bread is put on it?


Homework Equations





The Attempt at a Solution

 
Physics news on Phys.org
What are your thoughts on the matter?
 
as the mass increase moment of inertia increase so it slows down the system
am i right?
 
What equation in physics are you thinking of that says that?
 
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...
