What is the difference between walking and running? I've see people say it is whether a foot is alkways on the ground or not, and similar things.
Personally, i define walking as the feet pulling the body, and running as the feet are pushing the body. Thus, usually, the feet are in front of the person when walking (and behind when walking backwards) and the feet are behind when running (and in front when running backwards). I like this definition because it is very clear, and the distinction makes sense.
