... also the same as the energy (potential energy, PE) stored in the spring, and the work the stretched spring could do if released. In this lab, we will be converting this stored energy into kinetic energy (KE) of a glider on an air track, and calculate its velocity using the interface. Assuming there ...

Hooke`s Law and Potential Energy
... In this experiment we will neglect frictional terms and we will not do any work on the system between the two times we measure the energy. The energy of the system consists of the potential energy stored in the spring [Eq. (2)], the kinetic energy of the oscillating mass [KE = (1/2)mv 2], and the gr ...
