Rocket Energy
*
Purpose: we are trying to figure out where the potential engy we pull the Roband back and let it go it flys in the air
Materials:the materials was a plastic rocket and a Handel tied with a Roband on it
Method:we put the rocket on the robber band then we pulled the robber band back and we released the rocket to fly
Observations: when the rocket started to fly up in the air it came down
Conclusion: from this experiment where this energy is coming from it is first potrtenteil energy it's power comes from us pulling the robber band the energy turns into kinetic baceuse it was
Going to the rocket when we release the robber band the power is on the rocket for it to fly
