Rotation - what is angular velocity and angular acceleration? (terms used in Rotation) #1

Terms used in rotation are angular velocity, angular acceleration and angular displacement. They often have an interesting comparison with terms in linear motion.

However these are angular in nature (not linear) and are often expressed in terms of angle through which a rigid body moves about a certain axis of rotation.

ABOUT SCIENCE CUBE
The Science Cube is a channel dedicated to making concepts in physics easier for any student, be it one preparing for IIT JEE or NEET or an AP physics student.
Often important concepts in physics are understood partially but if a student makes an effort, these concepts can become very easy. It is particularly important for students pursuing IIT JEE, NEET and AP Physics to have complete conceptual clarity

So if you are a student looking for physics tutorials or free on line classes for physics for IIT JEE, NEET or AP physics, I would say you should subscribe to this channel.

Best wishes!

Thanks for the simplistic explanation! (and for the real-example demonstration).

Sir, I really like you explanation and methods. Your videos are really good for understanding the true beauty of physics.

Thank you for the perfect description of my most complicated concep

I have a simple question: if body has turned for 30pi radians in one direction, it would mean that angular distance = angular displacement. However, if body turned 20pi radians in one direction and 10pi radians in the other, angular distance would still be 30pi radians, but angular displacement 10pi radians. Is this correct?
