Full Idea

Helmholtz crucially asserted that all forces conserve the sum of kinetic and potential energy; superficially non-conservative forces like friction are simply macroscopic manifestations of more fundamental forces conserving energy at the micro-level.

A Reaction

Friction had been a problem case, because it appeared not to conserve energy when it slowed movement down.
