An upward acceleration results in a torque that pivots each component around its center of mass, causing the rotation of these components in an organized way leading to the transformation. A similar, yet much more complex process is happening when we use momentum. Consider different body segments as having distinct centers of mass. They are vessels for energy that you can use to transfer angular momentum to different body parts through different axes and planes of movement and / or rotation. #climbingtechniqueofthe21stcentury #kineticchain #switchpitchball #hoberman #juggling #climbingperformancecoaching #siliconvalley」11月9日 16時06分
