Right -- at the expense, but not at the expense of power itself. And not just at the expense of it. You can do it at the expense of the resistance of the support.
And the useful force would be the force of gravity, because all the rest is just reaction.
Well, you have been told about counteraction of a support for two days already! And it can counteract, if there is no friction, only vertically: you have two degrees of freedom, either to fall strictly on your ass or to bounce upward. That's it! Any other manoeuvre requires friction.
Well, you've been told about the opposition of the support for two days now! And it can counteract in the absence of friction only vertically: you have two degrees of self-obodiment - either to fall strictly on the ass, or to jump strictly upwards. That's it! Any other manoeuvre requires friction.
My centre of gravity is in the groin area (hussars, shut up!), about a metre off the ground. Depending on how steep the slope is, I either step or fall on my hands. In the latter case, the rule of three points of support starts to work, but the essence of the stepping mechanism does not change - I am always stepping, falling forward.

Well, well you are told about counteraction of a support for the second day! Only in the absence of friction this counteraction allows only to fall strictly on the ass, or to jump strictly upwards. To step in any side will require friction, or who will put a vertical support every time - then force of elasticity will do instead of friction:)
The bond was falling -- sorry for the doublet.
Yes ))) the force of friction moves a person. And there is no centrifugal force. And the earth is on three whales. Good luck with that.
And good health to you.
I never said (reread the thread) that gravity is not involved in walking. But it does help us. Imagine that gravity is halved - if it were a useful component of walking, then you are saying that in this situation it would be harder to walk.
This is already about the theory of evolution. "All progress in organic development is at the same time regress, for by fixing one line of development, it rejects alternatives" F. Engels, I will not vouch for the accuracy of the quote:)
By the way - it's not that clear-cut. Would it help us to move around if the acceleration of gravity decreased by a factor of 1,000?

Not unambiguously. The maximum possible frictional force (it is proportional to weight) will also decrease by a factor of 1000. And if the result is not enough to push off, then we will just slip. Otherwise, i.e. if we can still walk in principle - yes, it will be easier to move around.
Thanks for the luxury of communication:)
