I have three questions here, and I am a bit confused about what "relative to" means in this context:
1."A 1.91 kg ball is attached to a ceiling by a
3.28 m long string. The height of the room is
5.94 m .
The acceleration of gravity is 9.8 m/s2 .
What is the gravitational potential energy
associated with the ball relative to the ceiling?
Answer in units of J."
2. "What is its gravitational potential energy rel-
ative to the floor?
Answer in units of J."
3."What is its gravitational potential energy rel-
ative to a point at the same elevation as the
ball?
Answer in units of J."
I'm not looking for specific answers, I just need help interpreting the questions.
