Fisika adalah ilmu dasar yang mempelajari rahasia alam semesta, mulai dari partikel terkecil hingga galaksi yang sangat luas. Secara harfiah, namanya berasal dari bahasa Yunani physis yang berarti “alam”. Intinya, ilmu ini mencari tahu bagaimana materi, energi, ruang, dan waktu saling berinteraksi untuk membentuk segala sesuatu yang kamu lihat di dunia ini.
Fokus utama fisika adalah memahami hukum-hukum alam yang mengatur perilaku benda di sekitar kamu. Orang-orang yang mendedikasikan hidupnya untuk meneliti dan memecahkan misteri ini disebut sebagai fisikawan. Melalui kerja keras mereka, kita bisa memahami fenomena alam dengan lebih logis dan terukur.
