Carol tried to lift the boulder, but she could not lift it. Carol tried to push the tire, but she could not move it. Carol tried again and again. Finally, she decided to leave the tire alone and to go home. Carol was tired and upset. The next day, Carol complained to her science teacher. She said, “I did all that hard work for nothing! All that energy I spent, and the tire did not move even a little.” The teacher asked the class, “What do you think? Was work done to the tire?”
Who is right?
Melody said, “No. Carol transformed her energy into nothing.”
Tyler said, “Yes. Because Carol was tired.”
Rose said, “No. Because Carol pulled and pushed, but the rock did not move.”
Kevin said, “Yes. Because Carol used her energy to push on the rock.”
