Abdul Muqeet AhmadPHYS 1410-NV1 Navitas PHYSICS 1 LabInstructor’s Name: Mengying ShiRotational MotionJuly 29, 2016Partner’s Name: Huy Quang HuynhThe objective of the experiment is to apply known torques () to a system which if free torotate. The resulting angular acceleration () will be measured and used to determine theMoment of Inertia () of the system.
