Question

Eriq and Fatima are studying physics…

Eriq: I don’t think I believe this whole work-kinetic energy

theorem.

Fatima: Oh, really…

Eriq: For example, I helped my friend move a fridge into his dorm room the other day. We started outside, picked up the fridge, carried it up three flights of stairs, and then pushed it across the floor into place. But since the box started and ended at rest, I did no work on it, but I definitely was tired and sweaty.

What is wrong with Eriq’s thinking?
