Physics is regarded as one of the most primitive subjects and academic fields ever discovered. It encompasses the analysis of matter, its movement and behaviour, as well as energy and force. It intersects with a wide range of subjects and disciplines, including biophysics and quantum chemistry. Physics frequently defines a broad range of principles and techniques investigated by other branches of science. It also suggests new research directions for other fields of study, including mathematics and philosophy. This means that anyone interested in a foundation in physics course in malaysia has many options.
Physics is made up of numerous interdisciplinary subjects and branches. These are a few.
The two main theories of modern physics are relativity and quantum mechanics. This branch of physics was pioneered by Albert Einstein and Max Plank. They were the first to propose relativity theory and quantum mechanics. Unlike the classical branch of physics, modern physics does not regard energy and matter as distinct entities. They are only referred to as the two distinct ways of each other in this context.
Atomic physics is another branch of physics. It is concerned with the atom’s composition other than the nucleus. Its primary goal is to investigate and comprehend the actions of electrons in the shells surrounding the nucleus. This area of physics is concerned with electrons, ions, and neutral atoms. One of the first and most important forays into atomic physics was the realisation that all matter is made up of atoms. The discovery of spectral lines marks the beginning of atomic physics. This discovery led to a completely new study of the mechanism and arrangement of atoms.
Mechanics is a branch of physics concerned with the movement and motion of physical things when subjected to a force and when at rest. It investigates the relationship between various concepts such as force, matter, and motion. Pressure exerted to objects causes displacements or changes in an object’s position in relation to its surroundings. It investigates the laws of motion, gravitation, friction, displacement, and forces, energy, and power.
Acoustics is the study of sound in physics. It investigates mechanical waves as they travel through various media such as gases, liquids, and solids. It investigates vibrations and focuses on sound engineering, control, transmission, reception, and effects. It investigates concepts such as vibration, sound, ultrasound, and infrared.
Optics is a major branch of physics that analyses light and its characteristics. Optics is the study of behaviour, light properties, light interactions with matter, and modifications in these activities and interactions. The branch investigates the properties of visible, ultraviolet, and infrared light. Physical and geometrical optics are the two branches of the field. Physical science is related to the nature of light and other properties, whereas geometrical science is concerned with light interactions with lenses, mirrors, and other devices.
Thermodynamics is the study of heat and other forms of energy in physics. It is concerned with the transformation of energy from one form to another. It was invented in the nineteenth century while scientists were working on steam engines. The basis of the branch is built on three thermodynamic laws.
