  1. How Does the Original Potential Energy Affect the Length of Time a Newton’s Cradle Swings? Paul Halford Richardson AP Physics

  2. What I Tested • I tested how long a Newton’s Cradle took to completely stop after I gave it some known potential energy.

  3. How I did It • I began by defining what potential energy I wanted to give the ball each time. I started at one centimeter from my reference point and moved upward at intervals of one centimeter. • Then a stopwatch was used to record how long the system remained in motion. • This data was then graphed

  6. The Data

  7. The Analysis • As you can see, this data is far from linear, resembling a logarithmic. Reasoning behind this could include a multitude of things from the formula for the period of a pendulum to the fact that the metal compresses similar to a spring. After looking at the sound energy dissipated by the system, we see that the majority of the energy is not dissipated by sound.

  8. The Conclusion • Because of this data we can conclude that as we increase the potential energy, the time increases logarithmically. Because of this, the total Power of the system increases as we add to the original potential energy.
