Frame of reference and Newton's third law

AI Thread Summary
In a rotating frame of reference, Newton's first and second laws hold true when a fictitious force equal to mv^2/r is considered. This assumption does not compromise the validity of Newton's third law, which asserts that every action has an equal and opposite reaction. The presence of fictitious forces does not alter the fundamental relationship between forces exerted by interacting objects. Thus, Newton's third law remains applicable in both inertial and non-inertial frames of reference. The discussion confirms that the law's validity is maintained despite the introduction of fictitious forces.

I can not find the answer for this

In a rotating frame of reference, Newton's first and second laws remain valid if we assume that a fictitious force equal to mv^2/r is acting. What effect does this assumption have on the validity of Newton's 3rd law?

What do you think the effect is? If you always have to add a force to anything that's happening?
 


The assumption of a fictitious force in a rotating frame of reference does not affect the validity of Newton's third law. This law states that for every action, there is an equal and opposite reaction. In other words, when one object exerts a force on another object, the second object exerts an equal and opposite force on the first object.

This remains true even in a rotating frame of reference, where the fictitious force may be present. The forces between objects in a system are still equal and opposite, regardless of the frame of reference. Therefore, Newton's third law remains valid in both inertial and non-inertial frames of reference.
 
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 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
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...
