AI Thread Summary
The discussion centers on confusion regarding equations related to angular velocity and rotational forces. Participants seek resources that provide comprehensive lists of relevant equations and educational materials on the topic. Key issues include understanding how mass factors into equations for centripetal force in scenarios like a ball on a string and a lack of clarity on the concept of angular velocity itself. A couple of helpful websites are suggested for further learning and clarification. Overall, the thread emphasizes the need for better resources to grasp these concepts effectively.

Ok guys, I am a bit confused on this.
Does anyone know a good site that has a list of equations for just this? (like angular velocity, etc?)
Or even better, a website that TEACHES it?

Like I seem to be running into 2 problems while doing this homework.
First of all, some questions are like "ball on string being rotated around, creating force of blah, what is the mass" etc, but I don't know any equations that have mass in them related to this.
The second issue is that I don't really understand angular velocity.

If anyone could please help me with my questions above, that'd be great.
thanks

When the ball is being spun around the centripetal force that it experiences by the string pulling it (the tension in the string) towards the center of ratation (your hand), it (the ball) will pull just as hard back on the string (N3 action-reaction). This force is transmitted by the string to your hand. The string will therefore pull just as hard on your hand as the centripetal force it experiences.
 

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...
