Barret Pickett Kennedy 4 th 1/10/2006 Conservation of Energy Purpose: to determine whether or not the mechanical energy in a mass – spring system is conserved. Background theory: ME = KE + PE, W = Fdcosθ, KE = 1/2mv 2 KE is energy in motion and PE is the potential energy of an object. The Mechanical Energy (ME) is equal to KE + PE, there for PE and KE are inversely related. In this lab, we will observe how KE transfers to PE and visa versa. Work is the outcome of forces and distances. Key Steps and important reminders: Determining the Spring Constant have supplies neatly set up – spring, scale, tape measure, rubber band, masses set up the Hooke’s Law apparatus set scale to 0.0cm and record how far it stretches find a mass that stretches the rubber band ¼ the way down and record the value of the mass and how far it has stretched perform several trials with increasing masses until the spring stretches to the
