On Forces active in the Golf Swing....

[no_mind_golfer]

How can golfers ever expect to get better if they don't understand root cause and are being misled by those who claim to understand .... but don't?

Muscle contractions cause forces on the levers of the human body. These forces, being unreacted, result in movement in accordance with Newtons F=MA where A is acceleration or first derivative of velocity. Changing velocity is acceleration and when there is a mass involved creates a force (or vice-versa). When there is no apposing force as in the golf swing we get MOVEMENT.

In dynamics, forces do not always come in pairs... Statics (no motion yes)... Dynamics (motion) NO. For example: there is no force apposing the thrust (FORCE) of a jet or rocket engine. Mass is expelled at velocity causing MOTION... F = (dM/dt * V) = MA.

Only pseudoscientists confuse internal loads with external loads aka the forces that cause movement.

Our bodies having mass are constantly subjected to a force (gravity)... What's the opposite of gravity? Anti-gravity? Only on Star Trek people. Without gravity our muscles atrophy and our bones leach calcium (which BTW creates a problem for long term space travel). Gravity causes a beneficial INTERNAL load (but its not called anti-gravity) on our bones and Muscles... BUT GRAVITY DOESN'T (necessarily) MAKE US MOVE! Get it? On to Golf.

In order for any object to move on a curvilinear path, it must be subjected to an acceleration. There is a name for that acceleration that causes a change in direction: centripetal. When that object on a curvilinear path has mass, a force is involved: CENTRIPETAL FORCE. Only uneducated individuals refer to the internals loads imposed on a structure by centripetal force as CENTRIFUGAL FORCES.....

Educated individuals know that the CENTRIFUGAL force is an imaginary one (a fudge factor) that is only used when non-inertial coordinate systems are being analyzed. Any pseudo-golf scientist that tries to tell you that centrifugal force causes motion or is in any way involved in the golf swing ... is blowing smoke up your .... backside. It takes a lot of gaul for said psuedo-scientist to claim Cambridge University's physicists know not what they speak.... absolutely ludicrous when you think about it....

Centrifugal force is not operant in the golf swing. When you hear mention of centrifugal force with respect to the golf swing know that you're dealing with a posuer and move on. Humor him if his ego demands it but move on for there can be no reasoning with the ignorant.
