The second example is conceptually cristalline: if we were on the circle (embedded in R^2), the acceleration along the curve would be calculated by the ordinary second derivative and then *projecting * to the tangent space to $S^1$. The latter makes the acceleration zero. If, instead, you inflate the circle, you don't project anymore, and you get a big acceleration, no matter what you do. | |
