AI Thread Summary
When the net force on a system of particles is zero, the acceleration of the center of mass (COM) remains constant, while the momentum of the COM is also constant. The velocity of the COM can be constant or zero, and the velocity of individual particles may vary but can also be constant. The discussion highlights the relationships between these variables, emphasizing that multiple entries from Table 2 can correspond to a single entry in Table 1. Clarification is sought on whether more than two entries can match with one on the left. Understanding these concepts is crucial for analyzing systems in physics.

Q 5 Match the column
If net force on a system of particles is zero then
Table 1 Table 2

a) acc. of COM p) constant

b)momentum of COM q)zero

c)velocity of COM r) may be zero

d)velocity of individual particles s) may be constant

Ans is 5>a - pq, b - pr, c-pr, d-rs

a - pq is not correct.

Can you match more than two on the right with one on the left?
 

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'

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...
