I A Question on Spinors in a High school textbook

Click For Summary
Spinors are mathematical objects used in physics, particularly in quantum mechanics and relativity, to describe the state of particles with intrinsic angular momentum, or spin. They differ from traditional vectors in that they require a more complex framework for their representation, often involving multi-dimensional spaces. The discussion highlights a specific question related to spinors, emphasizing the need for a clear and comprehensible definition suitable for high school students. Visual aids, such as diagrams or gifs, can enhance understanding by illustrating how spinors operate in relation to other physical concepts. Overall, the inquiry seeks to demystify spinors and make the topic accessible to learners at an introductory level.

Question from Resnick Halliday Krane Chapter 8: Rotational kinematics
While revising Rotational motion, I came across a qualitative question which blew me away. Meaning I couldn't even understand the question let alone answer it😅. It has to do with these objects called spinors which as I understand are evoked in quantum mechanics and Relativity. I am attaching the question so kindly go through it. It would be really helpful if you could give me a rough idea of what spinors are. If you could throw in a visualisation or gif then even better. It's question no. 9 .

The spinor in tnis case is shown in the diagram. It's not directly related to QM.
 
So what exactly is a spinor? Like can you give me a definition which would be comprehensible to me at this stage?

The problem deals with the object in diagram 8-13. For the purposes of this exercise, that is the definition of a spinor.
 
Thread 'Why higher speeds need more power if backward force is the same?'

Thread 'Why higher speeds need more power if backward force is the same?'

Power = Force v Speed Power of my horse = 104kgx9.81m/s^2 x 0.732m/s = 1HP =746W Force/tension in rope stay the same if horse run at 0.73m/s or at 15m/s, so why then horse need to be more powerfull to pull at higher speed even if backward force at him(rope tension) stay the same? I understand that if I increase weight, it is hrader for horse to pull at higher speed because now is backward force increased, but don't understand why is harder to pull at higher speed if weight(backward force)...
