Purpose: To investigate the stored energy in a stretched spring and observe its conversion to kinetic energy. Equipment: Air track and glider, pulley, string Light spring Computer Photogate Mass set Principles: If forces acting on a system are conservative forces, then the sum of the kinetic and potential energies of the system is constant. Conservative forces are dependant only on the initial and final positions of a body such as the force of gravity. In this experiment we used the equation Work=1/2k(X-Xo) ^2. K represents the spring constant in N/m, X-Xo represents the change in the length of the spring. The potential energy and the kinetic energy are equal for the conservative force. (P.E.)i=(K.E.)f or 1/2k(X-Xo) ^2=1/2Mv^2 where M is equal to the mass of the glider and v is the constant velocity after the spring has relaxed. Procedure
