This question saying basically how much, how is it that you can add so much energy to a batted baseball when you can't really add much energy to it if you're just throwing it.
00:09
So if you're just throwing it, then you just have the force of the fingers on the ball.
00:14
Um, so if you try to throw a ball, for example, without moving your arms, you know, wouldn't really go really far because your fingers really aren't very massive, can't produce much of, uh, can't produce much, uh, momentum transfer and much energy transfer.
00:30
But with a bat, what you can do is you can think about the collision between a bat and a ball.
00:38
If the bat is moving at a high speed, it has a bigger mass in the ball, and it can also have a large velocity.
00:48
And so it can have a lot of momentum.
00:50
So you have, so you have the, let's say, the bat has some momentum this way.
00:57
And then the ball has just some momentum this way, the pitcher's not going to throw it as fast as possible...
