The Direction of Force That Makes the Board Flip Most Efficiently (Physics)

Every object in this world has three axes: vertical, horizontal, and depth—and a skateboard is no exception. Here, let’s call the longest axis connecting the nose and tail the Y-axis. From a physics perspective, just like a kickflip, a heelflip works most efficiently when force is applied perpendicular to the board’s axis of rotation. In practice, since you press the nose downward while the board is floating in the air, the board rotates along the Y-axis while the nose drops and the tail rises, leveling out horizontally.
