AI Thread Summary
The discussion focuses on identifying correct wordings of Newton's First and Third Laws. The accurate phrasing for the First Law is that an object in motion remains in motion unless acted upon by a force. The Third Law is correctly stated as when two objects interact, they experience equal and opposite forces. Other proposed statements, such as "objects always fall" and "what goes up, must come down," are not accurate representations of Newton's laws. The consensus confirms the correct formulations of the laws as stated.

1. Which of these are possible wording of Newton's Three Laws? Pick which ones are correct.

Objects always fall.
An object in motion always stays in motion unless acted upon by a force.
When two objects interact, they experience equal and opposite forces.
What goes up, must come down.
An object in motion only stays in motion if acted on by a force.


3. I think it would be just these:
An object in motion always stays in motion unless acted upon by a force. (1st)
When two objects interact, they experience equal and opposite forces. (3rd)

looks right to me
 
Thanks!
 
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...
