Answer 1

As the roller coaster car travels from Point A to Point B, it typically descends, which means its height and therefore its gravitational potential energy decreases. Instead, this energy is generally transformed into kinetic energy as the car speeds up.

Based on the options given, the correct answer is:

**A. The car's gravitational potential energy is transformed into kinetic energy.**

This indicates that as the car moves downwards, it loses potential energy and gains kinetic energy, resulting in an increase in speed.
