The classical condition
Mars in Libra is detriment: the planet stands opposite one of its own signs, which the tradition calls detriment: it has to work in a manner that is not native to it, which is a description of the working conditions and not of the person. Libra is ruled by Venus, so Venus is this Mars's dispositor: where Venus sits and how it is placed changes how the placement actually runs.
Detriment is the planet working against its sign's grain. Mars decides and separates; Libra weighs and joins. The classical result is force that has to be justified before it can be applied, which slows it and makes it more accountable. The older authors describe this as a Mars that fights fairly, and they mean both halves of that.
Venus disposes the placement, and traditional practice reads a malefic under a benefic's rule as moderated rather than crippled. The specific cost is timing: a Mars that consults before acting arrives after the moment, and where Venus sits says how much that actually happens.
Energy style
In practice this reads as force applied through others. Energy goes into arrangement, persuasion and the fair distribution of effort rather than into direct push, and the mode is the negotiation. Anger is deferred and expressed indirectly, and the classical caution is resentment, which is what deferred anger becomes when it never finds a form.

Why is Mars in detriment in Libra?
Because Libra sits opposite Aries, one of Mars's own signs. Every detriment lies opposite a domicile.
Is Mars in Libra passive?
Tradition reads it as indirect rather than passive. Force is applied through arrangement and persuasion instead of directly, which is slower and more accountable, and its dispositor Venus moderates rather than removes it.
