Angular Acceleration explained with Examples | rad/s^2 |Physics

What happens when velocity increases over time? Does the acceleration increase when velocity remains constant and what happens to the acceleration when velocity decreases? Is the direction of acceleration the same as that of the velocity?
Do you know how angular acceleration is represented? What's the unit of it? What are its different types? How do the types differ? To get to know about all of this in light of daily life examples, continue watching this video!
Quiz:
Answer:(a)As we know that,a=wf-wi/t
By putting the values:(26-4)rad/s/4s=22 rad/s/4s=11/2 rad/s2
Direction:The direction will be upwards,along the direction of angular motion.
(b) The angular acceleration will be zero because the final and initial velocities are not changing i.e wf=wi.
As by the formula:
a=wf-wi/t=(26-26)rad/s/4s=0
Direction:No direction because there is the acceleration is zero.

Physics is so easy. Thanks smartitute👌
