Friction on a pivot. Graph of motion w/ c.angular accel.

AI Thread Summary
Applied friction on a pivot will cause a rotating object to slow down, as friction typically opposes motion. The discussion highlights that while friction affects linear motion, it also impacts rotational dynamics. A graph of angular speed with constant angular acceleration will appear as a straight line, indicating a consistent increase in speed over time. This relationship mirrors that of linear motion, where position, speed, and acceleration follow similar equations. Understanding the effects of friction on rotation is crucial for analyzing motion in physics.

Quick question, if an applied friction is applied on a pivot, will a rotating object slow down? or nothing will happen?


Friction usually slows down objects in linear motions, but I don't know what it does on rotating objects.

What does a graph of a angular speed look like with constant angular acceleration?

yes, there'll be a frictional https://www.physicsforums.com/library.php?do=view_item&itemid=175" :smile:

a graph of angular speed against time will be a straight line

(basically, angle and angular speed and angular acceleration obey exactly the same equations as position and ordinary speed and ordinary acceleration)

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'

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...
