Please, pseudo scientists, do not randomly grab a descipline such as physics and find an example to suit your need. The very basic premise of an object in motion is that at the moment that object changes course (direction) from linear to rotation or vice versa, any kinetic energy that was built up to that point is lost according to the degree of directional change.

If done properly the stride forward could be used as a force to begin rotation of the lead hip, yet not happening simultaneously.

> Dennis. With regard to BHL's argument, you might if possible observe the swing of former major league player Mark Whiten. As you may well now, Whiten hit 4 homeruns in one game and drove in 12 runs. But if you observe his side view swing, he sweeps the bat through the zone using mostly a linear push. But his follow through is rotation per its finish by which he golfs 4 homeruns. It is also interesting to observe that he uses no inward knee turn to gather strength and no torque forces from the naked eye. And in my opinion it is likely that his homeruns would have traveled much further if he had more optimum swing mechanics. But at 6ft 3in 215 lbs it is likely that his raw power was considered adequate. If you have MLB.COM you can view what I saw.

Hi All,

George stated my position accurately. Although I am not a proponent of converting linear to rotational energy to generate optimum distance, I agree that it can be done. Just look at the early years of Frank Thomas.

Note: I am in the Ted Williams camp when it comes to hitting.
