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. In this example, the motor was used to convert ____________ to ___________.

• electrical energy... kinetic energy
• kinetic energy... electrical energy
