One of the key aspects of bat performance is the coefficient of restitution (COR), which measures the amount of energy transferred from the bat to the ball upon impact. A higher COR means that more energy is transferred, resulting in a faster ball speed and greater distance. Wooden bats tend to have a lower COR than aluminum bats, which is one reason why aluminum bats are known for their power.Bida 3 băng là môn thể thao sử dụng bàn bida không có l
