I need to look at terminology, so im going to make sure I have these concepts and ill just paste them as I look them up to save anyone else interested the time... - The line of compression is the direction of the impact force. - Force is the capacity to do work or cause physical change; energy, strength, or active power. - A Force is equal to mass times acceleration per newtons 2nd law - Acceleration is the rate of change of velocity with respect to time. - Velocity is a vector quantity whose magnitude is a body's speed and whose direction is the body's direction of motion. - Vector is a quantity, completely specified by a magnitude and a direction. - Magnitude is the greatness in significance. Ok question time relating to these terms.... To maintain a certain velocity of anything, it is always accelerating ? For a given force when a collision occurs, the force transfered by the acceleration really means the velocity created by that acceleration at that moment in time? A ball whirling around like in my picture post above - since the velocity or acceleration (discounting the other forces just now) is always tangential to the orbit, then the force of that ball hitting anything (tangential force I assume) is also going to be tangential to its orbit? and if this is true - then the direction of the clubhead force (keeping the clubface seperate for just now) traveling in its orbit should be tangential to the clubhead orbit?
