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 trains kinetic energy changed? the train was stopped, and then it began to move forward and away from the station. electricity started flowing to the motor when the ride operator flipped the switch.
Answer
Brief Explanations:
Kinetic energy is energy of motion. When the train moves from being stopped to moving forward, its motion changes, indicating a change in kinetic energy. Electricity flowing to the motor is a cause - not evidence of the change in kinetic energy itself.
Answer:
The train was stopped, and then it began to move forward and away from the station.
