Answer 1

The best answer that describes the energy changes during Rebecca's time on the slide is:

potential → kinetic → potential

Here's the reasoning:

1. Potential Energy at the Top: When Rebecca is at the top of the slide, she has gravitational potential energy due to her height.
2. Kinetic Energy During the Slide: As she slides down, her potential energy is converted into kinetic energy, causing her to accelerate and move down the slide.
3. Potential Energy in the Pool: When she enters the pool, she can momentarily have some potential energy again, depending on the height above the water surface, but primarily her kinetic energy is converted into mechanical energy (energy of motion, splashing, etc.) as she enters the water.

Thus, the sequence of energy changes is best described as potential energy transforming into kinetic energy when she slides down.
