Ответ:

Нет, не одинаков.

Объяснение:

Механизм механических часов приводится в действие упругой силой пружины. При заводе часов пружина запасает энергию за счет скручивания (сжатия). По мере работы часов пружина распрямляется (раскручивается), ее энергия уменьшается. За счет расходования энергии пружины осуществляется ход часов (работа часового механизма). Таким образом, если подзавода часов не производили, то запас энергии пружины механических часов утром будет больше, чем вечером того же дня.
