1 Objectives: The objective of this lab was to reaffirm that momentum is always conserved when there is no net external force acting upon it. We also tested that energy is only sometimes conserved in various collisions. Experimental Data: Collision m1 m2 v1i v2i v1f v2f Inelastic #1 m1 = m2 .2641 kg .2644 kg .348 m/s 0 .171 m/s .171 m/s Inelastic #2 m1 < m2 .2641 kg .5144 kg .417 m/s 0 .138 m/s .138 m/s Elastic #1 m1 = m2 .2641 kg .2644 kg .344 m/s 0 0 .34 m/s Elastic #2 m1 < m2 .2641 kg .5144 kg .518 m/s 0 -0.127 m/s .326 m/s Data Analysis: 1) Initial and final momentum with kinetic energy: Collision 1: 𝜌 𝑖 = 𝑚 1 ∗ 𝑣 1𝑖 𝜌 𝑖 = .2641(𝑘𝑔) ∗ .348( 𝑚 𝑠 ) 𝜌 𝑖 = .092(𝑘𝑔 ∗ 𝑚 𝑠 ) 𝜌 ? = (𝑚 1𝑖 + 𝑚 2 ) ∗ 𝑣 ? 𝜌 ? = (. 2641 + .2644)(𝑘𝑔) ∗ .171( 𝑚 𝑠 ) 𝜌 ? = .090(𝑘𝑔 ∗ 𝑚 𝑠 ) Collision 3: 𝜌 𝑖 = 𝑚 1𝑖 ∗ 𝑣 1𝑖 𝜌 𝑖 = .2641 (𝑘𝑔) ∗ .344( 𝑚 𝑠 )

    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.
