Should you always apply the rules of significant figures?

AI Thread Summary
Applying the rules of significant figures is essential in physics, chemistry, and mathematics computations, including homework problems. Significant figures help ensure precision and accuracy in calculations, reflecting the reliability of measurements. While some may argue that these rules are only necessary in labs, they are equally important in theoretical work to maintain consistency. Ignoring significant figures can lead to misleading results and a lack of clarity in scientific communication. Therefore, significant figures should be applied universally in both practical and theoretical contexts.

Should you apply the rules of significant figures when you are doing any kind of physics, chemistry, or mathematics computation? Like, for example if you are doing homework problems in your textbook, should you still follow the sig fig rules or should you only apply them in labs and measurements?

For physics and chemistry, you should be using significant figures in your homework problems too. Why wouldn't you?
 
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...
