Lab 125 – Conservation of Energy Using Spring-Mass System Physics 111A Mario DeLaPaz November 3, 2010 Kui Chen Objective : To verify the conservative of mechanical energy in an oscillating mass-spring system. Theoretical background: The total mechanical energy of the spring mass system is: ME = ½ mv 2 + ½ k(x 0 -x) 2 +mgx By deriving the first equation you could use : ME = ½ mv 2 + ½ (h-h 0 ) 2 +(mg) 2 /2k Since the last term on the right hand is a constant, the sum of the first two terms on the right hand side must be a constant for mechanical energy to be conserved. Equipment: Computer with ULI interface, motion detecter with tripod, right clamp and fork to hold it, Cylindrical spring, Standard set of weights, Weight hanger with a large diameter, Scale on the counter Procedure : For part 1, attach the large diameter weight hanger to a spring then connect motion detector to the port 2 ULI interface. Position the motion detector below the weight hanger.

### 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.
