Gravitational Potential Energy (G.P.E.) is related to Elastic Potential Energy(E.P.E.). The only way E.P.E is more related to G.P.E. is the more the E.P.E. the more G.P.E. When the amount of stretch was only 3cm the average height was 1.7m. as soon as the amount of stretch changed from 3cm to 1cm the average was .98m. Therefore E.P.E s equals G.P.E.
Even though the tests were done in the same enviroment, the rubber band that we used broke. Hence the new rubberband may have been stronger or weaker. Also when we, my partner and I, shot the rocket up we were off by 5 or 6 cm.Thirdly, we couldn't see if the stretch was 5 or 6 .This lab should have been done outside or inside on the staircase. The lab Soaring Straws was fun and understandable.
