Physics journal #6


At senior camp, we played this high calibur table game uniquely designed for the 21st century lifestyle. This game is called bulletball, and the objective of the game is to get the ball (or some kind of object) past your opponent by utilizing your forearm and/or hand. We played 6-man bulletball with water bottle that was provided at the camp. As we hit the bottle back and forth the table, i remembered that i could use my physics knowledge to analyze how this works in physics. As we hit the ball, we are using momentum and impulse. Momentum of an object is greater if the mass is greater and since the bottle we used were much greater than a ping pong ball that we normally use, the momentum was much greater. Also, just like the lab we did, as the bottle came to me, i thought to myself, if i hit the bottle to the other side and assume that velocity is positive, then the velocity of the bottle coming near me is negative. Therefore, if i apply a great force in that, i could hit the ball so much faster to my opponent. So i did apply a lot of force so i could hit the bottle with great velocity and get it past my opponents.
