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

[asz304]

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"

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)
