An elevatore is moving up with a constant velocity. Two different masses are attached to two different springs of same spring constant. Say you do two operations expanding the spring or compressing the spring by the same distance. Which operation consumes more energy: expanding the spring or compressing it?

Explanation

Both consume the same amount of energy assuming that the spring constants for both compression and expansion are same. This is because both the masses are at rest initially with respect to the car as the car moves with constant velocity.
