Introduction: The objective of this experiment was to see whether the oscillating mass-spring system would conserve mechanical energy. In this lab the equation used to solve mechanical energy is ME=.5mv^2+.5k(x o -x)^2+mgx . This equation then needs to be manipulated to ME=.5mv^2+.5kx^2+ ((mg)^2)/2k . When x=0 then the spring is placed at an equilibrium and when x<0, the mass has displaced past the equilibrium point. In order to find the spring constant you would use the equation F=kx . The force would the mass that is on the spring causing the spring to move. Procedure: Part I: 1. Equipment that are necessary for this lab are the following: 1 computer with a ULI interface, 1 motion detector, 1 thin wire spring, 1 standard set of weights, 1 weight holder with a large diameter, and 1 scale. 2.
