Item EG020003: For two objects that are the same distance from the center of the earth, the object with more gravitational potential energy weighs more.

Object 1 and Object 2 are the same distance from the center of the earth, but Object 1 has more gravitational potential energy than Object 2. Does Object 1 weigh more than, less than, or the same as Object 2?

  1. Object 1 weighs more than Object 2.
  2. Object 1 weighs less than Object 2.
  3. Object 1 weighs the same as Object 2.
