Document Summary

As we have covered in previous lectures, when the body is airborne it is not possible to apply reaction forces to it. Therefore 1) the center of mass follows a parabolic pathway and 2) the angular momentum is constant. However, this doesn"t mean we can"t use the angular momentum that is available to rotate in numerous ways while in the air. When in the air, rotation can occur about one, two or three of the principle axes simultaneously. The axis of rotation for each component of the rotation must pass through the center of mass. Vector going through center of mass out of the head then you take your right hand and figure out which way they"re rotating. In this scenario you"re somersaulting backwards while rotating with your right shoulder forward around an oblique axis (an axis that works for both planes of movement)
