Is walking just a constant state of falling?

Yes. Walking is controlled falling because you need to let go in order to move forward. If you never let your foot fall, your movements would be stilted and robotic. And according to medical engineers," When we walk normally we are constantly correcting tiny falls to keep ourselves stable."

Explanation:

The most ‘striking’ feature of the baseball is the stitches that interact with the air when the ball moves. Along with a slight effect on the air drag, there is a strong effect on the Magnus force. According to the stitch pattern, the Magnus force on a moving ball depends accordingly because the air interacts strongly with the raised stitches on the ball. Apart from this, the stitches provide a better grip for the pitcher and help in forcing the ball to move in different ways.
