Objectives The objective of this lab was to investigate conservation of linear momentum and energy in collisions in one dimension, both in elastic and inelastic collisions. The lab aims to show that momentum is always conserved when there is no net external force acting on the system and it will also show that energy is only sometimes conserved in various kinds of collisions. Experimental data Collision m 1 kg m 2 kg V 1i m/s V 2i m/s V 1f m/s V 2f m/s Elastic collision #1 0.266 0.266 0.912 0 0 0.899 Elastic collision #2 0.266 0.516 0.787 0 -0.235 0.528 Inelastic collision #1 0.266 0.266 0.974 0 0.474 0.474 Inelastic collision #2 0.266 0.516 1.03 0 0.336 0.336 Data analysis Derive eqn (6), for elastic collisions For m 1 =m 2 (v 2f -v 1f )/(v i2 -v i1 ) V 2f =0.899 V 1f =0 V i2 =0 V i1 =0.912 Hence, (0.899-0)/ (0-0.912) =0.899/-0.912 =-0.9857 For m 1 <m 2 V 2f =0.528 V 1f =-0.235 V i2 =0 V i1 =0.787 Hence,(0.528-(-0.235))/(0-0.787)

### 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.
