click the blue text to correct the passage about energy transformations during the roller coaster ride.\n\nat the beginning of the ride, the motor converted electrical energy into kinetic energy. this caused the train to move out of the station and over the first hill.\n\nas the train went down the first hill, kinetic energy was converted into gravitational potential energy. next, as the train went up the second hill, kinetic energy was converted into gravitational potential energy. then, the train went down the second hill and moved back toward the station.\n\nfinally, when the brakes squealed and heated up at the end of the ride, sound energy was converted into kinetic energy and thermal energy.

Answer

Brief Explanations:

  1. First blue text correction: A motor at the start of a roller - coaster ride should convert electrical energy into gravitational potential energy (to lift the train to the top of the first hill), not kinetic energy.
  2. Second blue text correction: When the train goes down the first hill, gravitational potential energy is converted into kinetic energy (as height decreases and speed increases), not the other way around.
  3. Third blue text correction: When the train goes up the second hill, kinetic energy is converted into gravitational potential energy (this part is correct, no change).
  4. Fourth blue text correction: When the brakes heat up and squeal at the end, kinetic energy (of the moving train) is converted into sound energy and thermal energy, not sound energy being converted into kinetic and thermal energy.

Answer:

  • "electrical energy into kinetic energy" should be "electrical energy into gravitational potential energy"
  • "kinetic energy was converted into gravitational potential energy" (when going down first hill) should be "gravitational potential energy was converted into kinetic energy"
  • "sound energy was converted into kinetic energy and thermal energy" should be "kinetic energy was converted into sound energy and thermal energy"
