<div style="margin: 0in 0in 0pt"><span style="font-size: 9pt">If you could be more specific about what aeronautic terminology that you think I have used incorrectly and what words I have used improperly maybe I would have a clue as to what you mean. The flight of a golf ball is more an aerodynamic phenomena as opposed to an aeronautical one. In controlled flight there is usually a pilot in charge of the controls. The pilot does not need to know the simple difference between lift and drag if he did there would be very few if any pilots. Lift is not drag but they are very similar. Lift and drag are infinite in direction, either one can cause the motion of an object or oppose motion in any direction. Lift and drag are the two aerodynamic forces that are inflicted on solid objects by relative airflow. By accurate definition the only difference between lift and drag is there direction in relation the relative airflow that caused them. Lift is perpendicular to the relative airflow that caused it and drag is in the direction of the relative airflow that caused it. Relative airflow does not require the motion of air around a solid object or the motion of an object through air (flight path) or the motion of an object while in the air (rotation) although any one or combination of any can make up the relative airflow that influences a solid object. </span></div><div style="margin: 0in 0in 0pt"></div><div style="margin: 0in 0in 0pt"><span style="font-size: 9pt">I am not going to intentionally be less than accurate to avoid upsetting some one with misconceptions about basic aerodynamics or someone with no misconceptions about bias aerodynamics. If every one agreed there would be little to discuss and if you don&rsquo;t be more specific there will also be little to discuss. </span></div>
