1. The problem statement, all variables and given/known data none... Suppose a force acts on an object. the force does not vary with time, nor with the position or velocity of the object. Start with the general definition of work done by force, and show that the force is conservative 2. Relevant equations W = FX Wnonconservative = KE final PE final - KE initial - KE final 3. The attempt at a solution I started with W = FX W = E final - E initial E = KE f + PE f - KE i - PE i W = 0 + PE f - O - PE i Since KE is a non-conservation force and there is only a conservative force. W = PE f - PEi Since PE f = PE i if PE is a conservative force w = 0 The answer doesn't make any sense... Any suggestions?
