Purpose:We release the sling shot and then the energy went to the rocket then it turned to kinetic energy then it made drag gravity made it go down then made trajectory.
Materials:We us a sling shot and a rocket and rubberband.
Method:We pulled the rocket back then realease it then it went flying high up in the sky.
Observations: it went flying high up in the sky.
Conclusion:from this experement we learned lots of words like kinetic energy
