So what are those physics? Let's go back to dlirnlig through a wall. So you're applying a force on a dilrl towards the wall. And Newton says the wall is going to apply force back, equal and opposite. So, as you drill through the wall, those forces balance. But then there's that moment when the drill first punctures through the other side of the wall, and right at that mnmoet the wall can't push back anymore. But your brain hasn't reacted to that change in fcroe. So for that millisecond, or however long it takes you to react, you're still pushing, and that unbalanced force causes an acceleration, and that is the plunge. But what if right at the moment of puncture you could pull that tip back, actually oppose the forward aicctleeoran? That's what I set out to do.
