The principle of skateboarding is:

1. It uses the motion theory and mechanics of the human body, and uses the body's waist, hips, feet to twist and hand swings to drive forward.

2. The twisting of the human body will generate torque, and the static friction force will be generated between the wheel and the ground. Therefore, when the wheel rotates through an angle wheel around the axis of rotation, the static friction force between the wheel and the ground will be along the horizontal component of the moving direction of the person, thus Drive the skateboard forward.

Skateboarding is the originator of extreme sports history, and many extreme sports are now extended from skateboarding. Skateboarding, which evolved from surfing in the late 1950s and early 1960s, is now the coolest sport on the planet.
