This video demonstrates perfectly what we have learned about all week in AP-C Physics. It first starts off by saying impulse equals force times time. Then it goes on to say that that all is equal to the change in momentum. Those are the formulas we have been working with the past week, which we all call "Jimpulse." The example in the video is great in that it talks about the force applied by a bat to a baseball, and why bunts work the way they do. I always knew that bunts obviously make the ball go a shorter distance, but this video made me think about it in a physics way. Since the time the ball is touching the bat is less, the impulse will be less, and therefore, goes a short distance. In order to get a home run, and to maximize the impulse, you need to keep the bat in contact with the ball for as long as possible (have a good follow through). It all makes sense now to physics!
