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.
