Today we build our cars! It was crazy. After we build our cars we began to do our investigation. First, we wrapped the rubber band around the axle three times (added potential energy) and launched our car. Once the car stopped we measured how far it went. We did this three times, then we wrapped the rubber band 6 times and measure the distance it rolled. (Kinetic energy) We ran three trials of this as well, then we move on to 12 times and recorded our data. Tommorrow we will graph our data.
Qustions to consider: When you released the car, what kind of energy did it have?
In which trial do you think the car had the most energy?
