Which coin paradox calls for the ability to assess when more force is needed?

The answer to this question would be: the more force used, the less effective it is.

Sometimes, more force in counterinsurgency can cause a less effectivity. It was called paradox because with more force you should expect more results and more efficiency. But more force could mean higher possibility for collateral damage which can cause loss, not gain. An overwhelming force also might be pictured as brutality.

The thermodynamic determines the amount of chemical energy a substance has.
