Homework Help: How to build a solar mini car

  1. Mar 7, 2009 #1
    I am trying to build a solar mini car for a physics project. I have a 1.5-3 volt dc motor and a 1.5 volt solar panel. I have wheels and axels. I am confused about how to attach my motor to my wheels. Some websites say buy a small and large pulley and attach the small pulley to the motor and the large to the right axel and then use a rubber band to attach the pulleys but I dont understand how to. Other places say to buy gears but I have no idea how that works.

    If you understand how to attach my motor to my wheels please leave a post!!
