To find the percent error, I had to use the average of potential energy and kinetic energy and total energy. % Error = KE ETOT ETOT x 100 % Error = PEg ETOT ETOT x 100 .280 m .258 .258 x 100 = 8.52 .236 m .258 .258 x 100 =− 8.40 Conclusion: My hypothesis was correct because as altitude or height decreased, potential energy was lost and kinetic energy was gained. Kinetic energy was more than potential energy just by some difference when the height was decreasing. Even though, the difference was not that much, but kinetic energy was still higher than potential energy. The percent error for kinetic energy was 8.25% and potential energy was -8.40%. One of the sources of error in the lab could have been if the cart was not moved from the same height for each trail. Another source of error could have occurred because my team took the height measurement of Pasco senor only one time and used that to subtract for all the trails. This could have given me different numbers for the height for each trail than actual.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
