The due date for this assignment is past. Your work can be viewed below, but no changes can be made. 1. [MI2 05.X.25] 1/1 points Consider an isolated system, by which we mean a system free of external forces. If the sum of the particle energies in the system increases by 147 joules, what must have been the change U in the system's potential energy? U = -147 -147 J Solution or Explanation ( E particles + U ) = W ext Here, W ext = 0 because the system is isolated, so neccesarily U = - E particles . 2.
