Curve Mechanics Part 1| Lean into the curve
This is the reason why it will never be as easy to run as fast around a curve… as fast as you can in a straight line across the same distance. Naturally because there are other forces involved. As we run around a curve, the medio-lateral friction component of the GRF is starting to arise. And that occurs with every step that we take, which is a necessary thing. We need a certain magnitude of friction in a variety of sports and life situations… Like walking in general. And if we didn’t have it, it’d be like walking on ice all the time. But again, with enough friction on the running surface, if we were to remove that centripetal force we’re producing, we'd end up running in a straight line again, just like when we’re running out of a curve.
