F=ma Mass

AI Thread Summary

The discussion centers on the validity of Newton's second law, f=ma, in various scenarios and whether the mass of objects, like a frying pan, changes with temperature. It is noted that f=ma holds true under classical mechanics but may not apply in relativistic or quantum contexts. The question regarding the mass of a hot versus cold frying pan highlights the concept of thermal expansion, which can affect measurements but does not change the intrinsic mass. A forum member suggests reviewing existing resources for better understanding. Overall, the conversation emphasizes the need for foundational knowledge in physics to address these questions effectively.

help pleeeese~~ (validity of f=ma, mass of diff.temp objects)

:cry:

please help me~ desperate...

1. is f=ma valid in all situations? explain your reasons~
2. is the mass of a hot frying pan different from a cold frying pan? why?

thank you~~~

kiwikiwi: I see you've asked a number of questions, all of which look like verbatim from a textbook. Please read the sticky at the top of this homework forum.

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:
