Ключевые понятия и формулы: Физика CSCA
Все понятия программы вместе с формулами — и то, что на самом деле спрашивали на реальных экзаменах.
Экзамен CSCA сдаётся на китайском или английском языке — абитуриент выбирает сам. Поэтому понятия и формулы здесь даны на этих двух языках; на этой странице показан английский вариант.
