I have 3 questions regarding the topic:
1-Why is that we are allowed to add or subtract a constant to a potential energy function V(x) to set it to zero where it is constant?
2-What does adding/subtracting a constant physically correspond to if anything at all?
3- Do we do it simply for convenience ?
Thanks in advance
