Why does kinetic energy increase quadratically, not linearly, with speed? (2011)

https://i.sstatic.net/TeOX5.png
The kinetic energy of an object is proportional to the square of its velocity because it is a consequence of Newton's second law and the definition of work. The quadratic dependence of kinetic energy on velocity is a result of the symmetry properties of space and time, specifically the homogeneity and isotropy of space and the homogeneity of time.

Making Sense of Proof by Contradiction [pdf]

'contradiction' is not exactly the right word, as we don't directly contradict the initial statement. a proof of p2 = kq2 will have solutions for positive integer q if and only when j is square - but not for 2m2 or 6m2, even though m isn’t prime. this is equivalent to saying that 2q2, which is an odd power of 2, cannot possibly equal 2p2, is
