Does potential energy have a maximum value when the mass is at rest?
1 Answer
Not necessarily,
Suppose you have kept your book on the table,so it is at rest,and suppose it has an amount of potential energy
Now,if you put it on another table of height
So,see on both the tables the book was at rest but their condition at rest didn't let them have maximum potential energy,at both the positions.
Again you can think that while moving the book from one table to the other,if you cause the move with constant velocity
