Question
You pick up your physics textbook from the floor to read it, lift it about 0.3 m, carry it to your desk, sit down (the book stays at about the same height), and start reading.How much did the gravitational potential energy of the book change from when you picked it up off the floor to when you sat down and started to read? Question 4 options: A) 0 B) m * g * 0.3 m C) - m * g * 0.3 m D) We don't know because we don't know how far we carried the book. You pick up your physics textbook from the floor to read it, lift it about 0.3 m, carry it to your desk, sit down (the book stays at about the same height), and start reading.
