Students are investigating energy transfer in the laboratory. The students use rubber bands and rulers for their investigation. They attach a rubber band to each ruler, pull the band back, and allow the band to launch from the ruler. The diagram shows their set up. The results of their investigation are shown. Ruler Distance Band Is Pulled Back (centimeters) Distance Band Travels (centimeters) 1 5 61 2 10 122 3 15 213 4 20 366 Which statement best describes the results of their investigation? A. The more potential energy the band has, the more kinetic energy is transferred, and the farther the band travels. B. The less potential energy the band has, the more kinetic energy is transferred, and the farther the band travels. C. The more kinetic energy the band has, the more potential energy is transferred, and the farther the band travels. D. The less kinetic energy the band has, the more potential energy is transferred, and the farther the band travels.

This can be seen from the results of the investigation. As the distance the band is pulled back (which represents potential energy) increases, the distance the band travels (which represents kinetic energy) also increases. This shows that there is a direct relationship between the amount of potential energy and the amount of kinetic energy transferred, and the distance traveled by the band.
