Today you will use the sonic ranger and a force probe to study the energy transformations in an oscillating spring-mass system quantitatively. A force probe will be used to support the spring and mass, thereby, we can find the force acting on the mass at any time. The position  (necessary to find GPE and PE, respectively) will be monitored by a sonic ranger. We know that the mechanical energy (ME) is defined as the sum of the kinetic (KE), the gravitational potential energy (PEg) and the spring potential energy (PEsp).   The data will be analyzed using Logger Pro.  Logger Pro will provide you with position and velocity data as usual.  You will then create new columns to calculate the various energies from the position and velocity data.  Finally, an experimental check will be made of the Work-Energy theorem. If you don't remember the Work-Energy theorem, you should review before coming to lab.
