When people are balancing themselves on a surface where their feet do not provide a lot of balance (sidestepping a ledge of rope) they tend to wobble or swing their arms to maintain/regain balance. My question is, how does that work? When a person wobbles they move their hips outward and their upper body inward to try and reposition their center of gravity. But wouldn't their center of mass stay the same because of the conservation of momentum? Weight 1 goes one way and weight 2 goes the other way but the center of mass between the two doesn't change.
