Physics is crowned as the King of all sciences. It studies nature and matter - their properties, their motions, their behaviour, just to name a few. Ultimately, we study physics to gain a better understanding of the periodicity and patterns of the nature and the universe. So what do we learn in Physics? In the HKDSE curriculum, we aim to get a taste of the basics of various disciplines of the subjects: from studying the internal energy of objects in Heat and Energy, to investigating the motion of objects in Mechanics, while delving deep into the interaction of Electricity and Magnetism in later chapters.
