Physics? No. Normal Tetris rules. A tetromino stays where it lands.
Where a brick lands is defined as anywhere it makes contact with the ground in more than a single point, which explains why it keeps falling when the corner touches the curved floor, and stops once another corner touches. This also explains why a tetriomino is allowed to touch the corner of another tetronimo without connecting.
