Metric edit
Can we also get km/h speed conversions? Whilst ms-1 is fine for scientific literature, speeds are typically measured in km/h in metric nations, at least popularly. 60.242.48.18 (talk) 03:28, 6 January 2012 (UTC)

graph edit
Speed is literally measured by comparing time and distance. Is the graph "Time spent to accomplish a distance decreases predictably with increasing speed." really necessary? 82.16.58.234 (talk) 03:44, 16 August 2013 (UTC)
Gravity and Pendulum edit
I'm surprised there is no mention of gravity or a natural pendulum rhythm. As bipeds, we must balance on one leg while the other leg is moved. The free leg being moved will naturally move like a pendulum. The rate at which a pendulum moves is determined by its length and the strength of gravity. This naturally determines a walking speed given a typical stride length. Importantly, and also contradicting the article, it also means that slower speeds require more energy, because the walker must counter the pendulum motion.
