Web8 de nov. de 2024 · Example 2.4. 3. A block is attached to one end of a massless spring, the other end of which is attached to a vertical fixed peg in a frictionless horizontal surface. The block is spun around a circle, and the spring stretches as a result of this motion. In fact, the faster the motion, the more the spring stretches. WebAnd, therefore, there are no fine-tunings or hierarchy problem in a theory describing all observed phenomena in particle physics.
