Austin Green Lab Partner: Yi Ming Conclusions Summary: The main objective was to find the total initial and final momentums and compare the two data. If they are similar than your collision was successful and the momentum is considered conserved. I had all the momentum conserved on each collision. Determining the ratio of the final kinetic energy to initial kinetic energy shows whether the energy is conserved. Again, if they are similar than the energy is considered conserved. My two elastic collisions did not conserve energy, however my two inelastic collisions did. All of the units needed to have a standard deviation so that you could calculate all of the uncertainties and keep all the data correct.

Unformatted text preview: • Performing each of these collisions took many times to get correct data and to be able to find out whether energy and momentum were conserved on not on the two different types of collisions. Error Analysis: • With every calculation using uncertainties and sig figs, sometimes the data are not exactly right because of rounding and things to that sort. • Systematic errors can also be a possibility because of faulty equipment, calibrations, or the actual experimental design. • Also, every measurement used (especially time) could be subject to random error. • If the gliders are pushed too hard then they could possibly scrape the air track and mess up your time measurements....

    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.
