Purpose:We we're learning about pitentle energy and kinetic energy.
Materials:A plane a Handel and a rubber band on the Handel.
Method:1. we hook the plane on the rubber band
2. We pull back the plane on the rubber band
3.we let it go.
Observations:when I pulled the rubber band and when I letted it go it went slowly.
Conclusion:from this experiment where this energy is coming from it is first portenteil energy is power.
