The principles of swing are what baseball swing physics are after. Also, there has to be kept in mind that baseball swing physics are practically analyzing how the hitter shifts the weight from his back leg to his front leg as he steps into the pitch, after he sees the ball approaching him. Transferring considerable energy to the bat, the hitter then twists his body. While the hand and the bat initially traveling at 40 mph, the hand and the bat will travel in excess of 70 mph at the point when the bat meets the ball. Baseball swing physics have proven that even 1/100 sec may make a difference between a home run and a pop out, since the bat is swung at such a high speed. There has to be paid attention to the fact that there are many coaches advising hitters to "follow through", as this procedure has proven in many cases that it helps the hitter.

An important aspect which has to be taken into consideration is being represented by the fact that the hitter is considerably being helped to hit the ball by the up-mentioned procedure, as according to the calculations performed under baseball swing physics. Also, there has to be kept in mind that following through does insure proper positions and motions prior to swinging the bat, while it has no influence on the path of the baseball after it hits the ball. Therefore, this practically means that it is good for hitters to try to follow through the hit. There has to be paid attention to the fact that baseball swing physics are as well studying the proper position of the hands holding the bat, during the swing. It is important to be considered that, in the hitter's performance the position the hitter holds the bat is crucial.
