Micheal was at the gym and he was trying to lift the weights, but he could not lift it. Finally Micheal decided to go home. The next day he complained to the trainer that he did all that hard work for nothing! The trainer asked the other trainers "did he really do any work?"
Michelle: "Yes, because Micheal was tired"
Jose: "No, because Micheal transformed his energy into nothing."
Emily: No, Because Micheal pulled and pushed but the weight did not move."
Who was right?
Michelle
Jose
Emily
