The purpose of this lab is to learn about conservative and non-conservative forces using potential gravitational energy, potential spring energy, and kinetic energy. To find the spring constant, weights were added to the plunger until there was a displacement. Repeat five times with different weights and record the displacement. Then, the F (mg) versus displacement can be graphed, and the slope is k, which is used to find potential spring energy for the short, medium, and long ranges. Next, the launcher was placed at the tip of the measuring tape, and the maximum height of the launched ball was recorded for the short, medium, and long ranges. Five trials were performed for each launch position. The average maximum height was used to find the potential gravitational energy for each launch position. Last, the velocity of the short, medium, and long range launch positions were found using the two photogate method horizontally. The distance between the photogates (0.098 m) was divided by the average time to find the velocity for each launch range.

    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.
