Question
Few students take different reference states for zero potential energy. The changes in potential energy for two students is ____ .
- Same
- Different
- Depends strictly on choice of zero of potential
- Is indeterminate
Hint:
Change in potential energy is independent of the reference states.
The correct answer is: Same
- Potential energy depends on the reference state.
- But the change in potential energy will be same for all the reference states.
- So, the correct option is a.
- Potential energy is relative but the difference in potential energy is absolute.
