I Gravitational Illusions -- Two balls rolling down differently-shaped ramps

Click For Summary
The discussion centers on the concept of gravitational illusions, specifically how two balls roll down differently-shaped ramps. Participants emphasize the importance of hands-on problem-solving to truly understand the physics involved, rather than relying solely on mathematical proofs. The Brachistochrone curve is mentioned as a relevant mathematical solution to the problem of determining which ball reaches the bottom first. Contributors are encouraged to share their own mathematical solutions for feedback and discussion. Engaging with the problem directly is highlighted as essential for deeper learning.

Without this test,using only math, would you prove that left ball will comes first?

Thread 'Please Explain Elementary Physics Elevator Question'

Hello, I'm joining this forum to ask two questions which have nagged me for some time. I am in no way trolling. They both are presumed obvious, yet don't make sense to me. Nobody will explain their positions, which is...uh...aka science. I also have a thread for the other question. Yes, I'm questioning the most elementary physics question we're given in this world. The classic elevator in motion question: A person is standing on a scale in an elevator that is in constant motion...
