Usually we walk by friction, and roller skating needs the reaction force generated by the back pressure of the inner blade. So the essentials of roller skating are: hard feet, standing with splayed feet, upright upper body and slightly bent knees. Extend your feet in the direction of the roller skating tool rest. The above is the balance before and after.
For the balance between left and right, please refer to the physical simple pendulum motion mode. It is advisable for the upper body to keep the shoulders still, and the center of gravity needs to swing left and right, which requires a restoring force. Specific method: slide along a straight line, lift your right foot, land on the left side of the line and send it out. Similarly, put your left foot on the right side of the line and send it out. At this point, the head and shoulders are stationary, just above the line. Pay special attention to your shoulders and don't shake back and forth!
When turning, the upper body must drive the lower body to turn, and the upper body must turn first. And slightly inclines to the inner side of the rotation direction, and the component of gravity provides centripetal force. The faster the speed, the greater the inclination.
Practice of balancing and turning left and right: find a line, stop the two front wheels on the line, stand up straight, and separate your feet shoulder width apart. At this time, slowly move the center of gravity to one leg, and it is appropriate to align the tip of the nose, knees and toes. Proficiency in left-right interchange.
Lift your feet after proficiency, and stand with your feet crossed in parallel after landing. The center of gravity changes with the feet, and the upper body is upright and the knees are slightly bent during the whole process. When turning, the feet are not parallel when lifting the ground, which is about 135. Depending on the direction you want to turn, turn your upper body first and then decide.
