|What was the purpose of your experiment? Provide a brief description of what you were hoping to learn, discover, or study.:
|I was hoping to learn what happens to momentum when balls collide.
|What was your hypothesis?:
|That the balls would stop, all except for the one on the other end. It would keep going.
|What materials did you use in your experiment? List them all.:
|Three tennis balls.
|What procedure was followed? Provide a brief description of the steps you followed during your experiment.:
|I put two golf balls down. Then, I put the third about fifteen inches away from the other two. I rolled the third ball toward the other two.
|What were the results of your experiment?:
|The one on the other side started rolling.
|What is your conclusion after conducting the experiment? Was your hypothesis correct or incorrect?:
|My hypothesis was correct, the “first” ball started rolling.
|Spend a few minutes learning about the scientific principles involved in your experiment. Write 3-4 sentences about what you learned and how it relates to your experiment.:
|Another way to see the exact same effect would be called “Newton’s Cradle. It has five metal balls on strings connected to the same big line. When one hits it, the one on the other side starts going. Then it works the opposite way. It goes on pretty much forever, but due to friction, it will eventually stop. The three middle balls never move.
