A background story on how to use Newton’s Law for rotation
This trick is actually quite common. I wish I knew it before learning Newtonian Dynamics in rotations.
A rotation dynamic usually described using vectors. At first I find it quite awkward and foreign because it doesn’t follow exactly how Newton’s law in cartesian coordinate is being used. A simple example is how the Newton’s Law had to be modified using a vector cross product to describe the torque.
