1. A golf swing measurement and analysis system comprising:

  • a golf club comprising a shaft, a club head, and the club head further comprising a club head top surface and a club head face;

    a first module that is attachable to and detachable from said club head top surface, and comprises a means for measuring acceleration in three separate orthogonal directions defining a measurement axes coordinate system and transmitting acceleration measurements out of the first module wirelessly as first module transmitted measurements;

    a means for aligning said first module on said club head top surface defining an alignment of said first module, and a means for attaching said first module to a top surface of said club head top surface;

    a means for receiving first module transmitted measurements wirelessly at a computational engine external to said first module, the computational engine having typical input/output port formats and a display;

    a golf swing model stored on the computational engine comprising multiple levers including at least one rigid lever and at least one non-rigid lever, and a means for inputting constants based on a golfer and the golf club;

    a first computational algorithm that operates on said computational engine that interprets said first module transmitted measurements within boundary conditions of said golf swing model and detects if said first module alignment is misaligned and calibrates said first module transmitted measurements; and

    a second computational algorithm that operates on said computational engine that interprets said first module transmitted measurements or said first module transmitted measurements calibrated by the first computational algorithm within boundary conditions of said golf swing model to define dynamically changing relationships between an inertial axes coordinate system defined by said golf swing model and said measurement axes coordinate system during a golf swing.
