In an activity investigating forms of energy, a student is playing with a motor with a fan on it.  As the fan is moved, the gears in the motor also move.  Which of the following is a correct conclusion about the type of energy being used to move the motor and fan?

• When the motor moves mechanical energy is used.
• The light energy from the room causes the motor to move.
• Heat energy transferred from the gears causes the motor to move.
• The movement of the motor is caused by sound energy because the motor makes noise.
