Question
The roller coaster train slowly moved away from the station and over the top of a tall hill. As the train began to rush down the hill,the riders felt like they were rising out of their seats! The train sped up until the track flattened out at the bottom of the hill. At the bottom, the riders felt like they were being pushed down into their seats. Click the blue words to correct the statement. As the train rushed down the hill, the gravitational potential energy stored between the train and Earth stayed the same , and the kinetic energy of the train stayed the same.

The statement provided is incorrect. Let's correct it step by step:Step 1: Understand the concepts of gravitational potential energy and kinetic energy.- Gravitational potential energy is the energy an object possesses due to its position in a gravitational field. The higher the object, the more gravitational potential energy it has.- Kinetic energy is the energy of motion. The faster an object moves, the more kinetic energy it has.Step 2: Analyze the roller coaster's motion.- At the top of the hill, the roller coaster train has a lot of gravitational potential energy because it is at a high point in the gravitational field of the Earth.- As the train moves down the hill, it loses height, and therefore, its gravitational potential energy decreases.- The lost gravitational potential energy is converted into kinetic energy as the train speeds up.Step 3: Correct the statement.- The correct statement should reflect the conversion of energy types as the train moves down the hill.- As the train rushed down the hill, the gravitational potential energy stored between the train and Earth decreased, and the kinetic energy of the train increased.Final Answer: The corrected statement is "As the train rushed down the hill, the gravitational potential energy stored between the train and Earth decreased, and the kinetic energy of the train increased."
