PFO - BHL - ??

BHL – Again I find you are missing on several fronts with respect to PFO. To start, let’s evaluate a primary function of the swing – Energy. True energy, or perhaps transfer of true energy is one of the most important concepts in all physics and in other sciences where it can be defined in a traditional way, although not collectively correct, as "the capacity of doing work". Work in the truest definition, reduced to our topic heading of the baseball swing, can be from either side of the plate aimed or geared to either of the three fields…do you agree or disagree at this point – BHL? Moving forward, this simple definition is not very precise/valid for all kinds of energy, like energy associated with BHL heating up his dinner, but it is fairly correct for the mechanical energy as described in the baseball swing. Let me explain in simple BHL terms so you can understand. Action of a force that moves or displaces over a certain distance is defined as: "the product of the magnitude of displacement with the component of the force parallel to the displacement". Let me provide clarity BHL in the form of an equation: where 'W' denotes work, 'f' is the component of the force parallel to the net displacement d. In a more general form it is written as W=FdcosO , where F is the magnitude of the constant force, d the object displacement and 'O' the angle between the force and the net displacement. Remember BHL…that FcosO is precisely the F component parallel to d. Work is of course measured in Newton meters, unity that receives the name Joule (J). 1 J = 1 Nm. Using the BHL (black hole) rational of inserting other dynamic examples into the conventional baseball swing (place-kicker) let's use an exercise that translates kinetic and potential energy. Suppose A 40 kg bat (softball) is dragged 30 m on a horizontal infield (or football field), applying a Fp = 100 N exerted by said BHL. Such force acts doing a 60º angle. The field exerts a friction force Fr = 20 N. BHL…calculate the work done for each one of these forces Fp, Fr, the weight mg and the normal. Then calculate the net work done on the bat. The net result will be or can be evaluated…once converted from a drag concept or a place-kicking concept to a baseball hitting concept simply as: A well hit baseball travels equally over any of the three field fences. That is my point.
