Shifting the axis of rotation
The 360 flip requires the skater to scoop the tail backward while flicking the nose forward. This simultaneously triggers a pitch rotation (kickflip) and a yaw rotation (360-shuvit). The board spins on two axes, requiring precise timing to catch it mid-air.

nic Flicking the board off-center applies torque, causing it to flip along its longitudinal axis.
Fun Fact
Friction control: Skateboarders use paraffin wax on ledges to make concrete as slippery as ice.

center of mass (noun)
A point representing the mean position of the matter in a body or system. In 1989, Natas Kaupas shifted this point to spin atop a Santa Monica fire hydrant.
