How to determine the angular acceleration using the right hand rule?

Click For Summary
To determine angular acceleration using the right hand rule (RHR), the same principle applied for angular velocity can be utilized. Curling fingers in the direction of rotation, the thumb indicates the direction of angular velocity, while the angular acceleration can be found by applying the RHR to the cross product of angular velocity and radius. The discussion clarifies that clockwise and counterclockwise rotations correspond to specific directions of angular vectors. Understanding these directions is crucial for accurately representing angular acceleration in physics. The right hand rule effectively provides a visual method for determining these vector orientations.

How to determine the angular acceleration using the right hand rule??

I know how to get the direction of angular velocity using RHR. We curl up our fingers to the direction at which the object rotates relative to an aix and the thumb shows the direction. My question is, with the same analogy, how can we determine the angular acceleration using the right hand rule?? Adding to this, what does clockwise or anti cc suggest to the direction of angular vectors? THanks a lot to whoever contributes :)

Angular acceleration is ω^{2}r. You can represent it also as a cross product: ω\times(ω\timesr)

Now use the Right Hand Rule and you will come to the direction known for the angular acceleration.
 
For simple comparison, I think the same thought process can be followed as a block slides down a hill, - for block down hill, simple starting PE of mgh to final max KE 0.5mv^2 - comparing PE1 to max KE2 would result in finding the work friction did through the process. efficiency is just 100*KE2/PE1. If a mousetrap car travels along a flat surface, a starting PE of 0.5 k th^2 can be measured and maximum velocity of the car can also be measured. If energy efficiency is defined by...
