B. State whether each of the statements below is consistent with your results above. If not, cite a specific case from the table that contradicts the student's statement. Student 1: "The net work done on a system is always equal to the change in kinetic energy of that system." Student 2: "In the absence of friction, the total energy of a system must remain constant. In other words, K; + U; = Kf + Uf." %3D Student 3: "The total energy of a system can change if something is doing work on that system. The net work done on a system by external forces is equal to the change
