While true, your comment is focusing on what I think is the second most important aerodynamic force in a slip, which is the wind resistance if the side of the plane.

By far the most interesting thing going on is that you’ve destroyed lift. The ailerons are acting as spoilers essentially so the plane starts to want to drop out of the sky.

I’m a pilot, and the sensation of a slip is definitely not that you’re rapidly losing forward groundspeed, it’s that you’re suddenly not gliding, and instead kind of dropping out of the sky.

It feels different in different planes - I always felt the Cessnas were glued to the sky no matter how much I slipped, but the pipers would drop like a rock if I needed them to.
