@CarrudoDon@muskyhookset@Devin_Heroux You are mixing up surface manipulation with collision physics. A small lateral impulse on a low friction moving object absolutely changes its path, that is basic mechanics, not politics.
@CarrudoDon@muskyhookset@Devin_Heroux Low friction is exactly the point. If the coefficient is low, it takes less impulse to alter the velocity vector. Sweeping changes friction under the stone, yes, but a feather is not “sweeping,” it is direct momentum transfer.
@CarrudoDon@muskyhookset@Devin_Heroux None of that contradicts basic impulse and momentum. If anything, it reinforces that tiny force differences absolutely matter.
