Baseball swing physics have been trying, during the last decade, to show how a baseball player observes, process, decides, and swings the bat. Also, there has to be kept in mind that, according to baseball swing physics, it takes about 100 milliseconds for the eye of the batter to see the ball and send an image to the brain. Next, for the brain to process the information and gauge the speed and location of the pitch, it takes somewhere around 75 milliseconds. Then, the decision phase follows, where the batter has to decide whether to swing or let the ball go by. There has to be paid attention to the fact that, to pick a swing pattern, such as high, low, inside, outside, it takes another 25 milliseconds. According to baseball swing physics, when the bran sends signals to the legs to start the batter's stride, the swing starts, taking at least 15 milliseconds. During the next phase, which is the contact phase, the bat has to meet the 3-inch spinning ball within an eight of inch of dead center and at precisely the right millisecond.

An important aspect which has to be taken into consideration is being represented by the fact that, according to baseball swing physics, the swing itself takes 150 milliseconds. Also, there has to be kept in mind that the batter can stop during the first 50 milliseconds. The bat is moving too fast and the swing can not be checked, after 100 milliseconds have passed. According to baseball swing physics, moving a 2-pund bat at more than 80 mph is being involved with the swing, along with delivering up to nine horsepower of energy to the ball. It is important as well to be considered that the studies performed under baseball swing physics are bringing a significant contribution to the world of baseball nowadays.
