Hi there.
I was wondering if the universe is curved or if it is flat.
By the way, one other question.
When a person lifts an object the object gains Ep. Is the energy given to object by the person or does it gain energy by the Gravitational Field? even though i know that Forces (Gravity) cannot give or gain energy.
If a person was born on top of a mountain where would the Ep come from? Would it be from Gravitational Field?
