Read the same passage and think about the evidence that kinetic energy and gravitational potential energy changed.
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.
There are many types of energy. One type is kinetic energy, which is the energy an object has when it is moving.
Read the passage about the start of a roller coaster ride and think about the kinetic energy of the roller coaster train.
At an amusement park, a group of riders boarded a roller coaster train and sat down.
Once everyone was safely in their seats, the ride operator flipped a switch, and electricity flowed to a motor below the track. The motor pulled the train forward and out of the station.
Which of the following is better evidence that the train's kinetic energy changed?
In all energy transformations, the types of energy that decrease are converted into the types of energy that increase.
Read the same passage. Think about the energy transformation between kinetic energy, sound energy, and thermal energy.
The roller coaster train went through a final big turn and then headed back toward the station.
The train slowed down as brakes on the track squealed and heated up. Once the train came to a stop in the station, the riders stood up and left.
Based on what you learned about the roller coaster ride, which of the following statements about energy transformations are true? Select all that apply.
