Understanding Newton's Laws through an Experiment on Uniform Circular Motion

AI Thread Summary
The experiment on uniform circular motion demonstrates Newton's three laws of motion effectively. The first law is illustrated as the stopper remains in place until a force is applied, showing inertia. The second law relates to the acceleration of the stopper, which depends on the mass and the force exerted by the spinning motion. The third law can be explained through the action-reaction forces between the stopper and the weight, as they exert equal and opposite forces on each other. Clarification and further insights on these laws are sought to enhance understanding of the experiment's implications.

Homework Statement


I've done an experiment on uniform circular motion. Pretty much, there is a hollow tube and a strong goes through it. One one end is a stopper and on the other is a weight. I had to spin the stopper side, buy keeping hold of the hollow tube, keeping the string at a constant rotation.

I have to explain how this experiment illustrates all three of Newton's laws of motion.

Homework Equations


N/A

The Attempt at a Solution



First law: The stopper doesn't stay in motion when there is no force exerted on the spinning because of the weight on the other side.
Second law: The force is based on the mass of the stopper and the acceleration exerted by spinning.
Third law: Not too sure...Could someone please correct me if I'm wrong and provide their insight on all three laws?
Thank you, the help is very much appreciated.

Can someone please respond?
 
I know I'm double/triple posting, but I need some insight on this. Please, someone.
 
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...
