One experiment was performed at two different range settings to determine if kinetic energy is conserved after an inelastic collision. By shooting a ball into a pendulum and measuring the angle at which the pendulum had moved, the center of mass was calculated. The center of mass was then used to help calculate the velocity before and after the collisions. These velocities were in turn used to calculate the kinetic energy before and after the collision. Finally, using the velocity before the collision and the velocity after the collision, the percent of kinetic energy lost at both range settings were calculated. It was concluded from comparing the kinetic energies from before the collision to the kinetic energies after the collisions, that kinetic energy is not conserved in inelastic collisions. It was also concluded that as potential energy increases, kinetic energy decreases.

    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.
