BPF is the Bat Performance Factor. When a bat is tested, it is fixed in a stationery position. A ball is launched at a high speed towards the barrel of the bat. When the ball bounces off of the bat, the speed is recorded to find out how much faster it goes when it comes off of the bat. That is how the BPF is calculated. If the ball comes off of the bat at the same speed, the BPF is 1.00 If the ball comes off of the bat 20% faster, the BPF is 1.20
A metal bat will hit the hardest because metal is 85% stronger than a wooden bat.
because a metal bat has give so when the ball hits it the bat flex's and the ball slings off harder
BPF is bat performance factor or the bounciness of the bat. The higher the number the more bounce a bat has which translates to the ball coming off the bat with more speed and inertia. Sanctioning bodies limit the BPF typically to a 1.20 or less.
It means that the ball must come off of the bat under a certain speed.
No. A frozen baseball will die off the bat because the reason a baseball reacts to a bat is the connection between the ball and the bat. The bat will not affect the ball in the same way when the ball is frozen.. I recommend trying this because it will damage the bat.
The maximum speed in which a softball can come off the bat at in mph. (The bat's composition or structure is designed to limit the speed of the ball off the bat to 120mph)
It means that the ball must come off of the bat under a certain speed.
Studies have shown that the speed the ball travels after being hit by a metal bat is 3 to 8 miles per hour faster than a wood bat. This would translate to a ball hit for a home run travelling 20 to 50 feet further off a metal bat as opposed to a wood bat. Click on the 'Metal Bat vs Wood Bat' link on this page to read a very interesting article about these studies that were performed on the two different types of bats.
baseballs come off an aluminum bat faster and harder, than they do on a wooden bat. that is why in the MLB they make the players use wooden bats, to prevent serious injury. i myself perfer to use and practice with a wooden bat in the off season, because it teaches you to use the right mechanics to hit the ball harder and farther. but during games i use an aluminum ball bat, and during practice i use a wooden bat. i would restrain from using a carbon-fiber bat because they have a tendency to crack and break. but that is just my opinion on carbon fiber bats.
Yes, whether the batter attempted to contact the ball or not, if the ball strikes the bat and is fouled off, it is a strike, unless there are already two strikes, of course. If, on the other hand, the ball strikes the bat and goes into fair territory, the ball is in play, and the runner can attempt to reach first.
Generally, the bat is placed to meet the ball and little or no energy is added at point of contact by the bat, so the speed would depend mostly on the speed of the pitch, and the angle the ball comes off the bat.
