Due to better conditioning and to the influence of European players, the average game speed of an NHL(National Hockey League) skater has increased in the past decade. Since kinetic energy is proportional to the square of velocity, the likelihood of severe brain injuries from collisions at higher skating speeds does not increase in a linear fashion. If someone is driven head first into the boards with 10% more speed, then he will be smashing into the boards with (1+0.10)2 = 1.21 times or 21% more energy. read more
