Similar words 効こう 率りつ Often overlaps with 能率, but 効率 more broadly emphasizes the ratio of output to input, waste, or effectiveness of a method; 能率 often focuses on the pace or productivity of work.
生せい 産さん 性せい Means productivity, especially output per worker, time, or resource. 能率 can describe the efficiency of a particular task or way of working.
モーメント The common loanword for 'moment' in physics; 能率 is listed as a physics term for this sense, but outside technical context 能率 normally means efficiency.
Etymology A Sino-Japanese compound written with 能, associated with ability or capacity, and 率, associated with rate or proportion. This component explanation matches the ordinary meaning 'efficiency'; the exact historical development of the technical physics sense is not specified.
