The best answer that describes the energy changes during Rebecca's time on the slide is:
potential → kinetic → potential
Here's why:
- When Rebecca is at the top of the slide, she has potential energy due to her height.
- As she slides down, that potential energy is converted into kinetic energy, causing her to move faster.
- If she were to splash into the pool, the kinetic energy would convert back into potential energy as she comes to rest at the bottom of the slide, where her height is lower.
Thus, the energy changes can be summarized as potential energy converting to kinetic energy while she is sliding down and then back to potential energy at the bottom.
