The best answer that describes the energy changes during Rebecca's time on the slide is potential → kinetic → potential.
She starts with potential energy at the top, converts it to kinetic energy as she slides down, and when she reaches the bottom and is momentarily in the water, some of that kinetic energy can convert back to potential energy depending on the height of her position in the water. However, the primary focus is on the conversion from potential at the top to kinetic during the slide down.

The correct statement is potential energy at the top of the stairs; kinetic energy as she walks down.
At the top of the stairs, Kim has potential energy due to her height above the ground, and as she walks down, that potential energy is converted to kinetic energy as she moves.

The statement that best explains what makes Bobby's pinwheel spin is Energy from the wind pushes on the wheel causing the pinwheel to move.
Pinwheels typically turn when wind blows against them, using the force of the moving air to create motion.
