What is Physical Science?
Physical science is a discipline that studies natural science, dealing with non-living materials. The area of coverage includes physics, chemistry, earth sciences, geology, space science, astronomy, materials science, etc.
Branch of Physical Science
The 4 main branches of physical science are astronomy, physics, chemistry, and the Earth sciences, which include meteorology and geology.
Chemistry – the study of the composition, structure, properties and changes of matter. In this field, chemistry addresses topics such as the properties of individual atoms, the way atoms form chemical bonds in the formation of compounds, the interactions of substances through intermolecular forces to give them their general properties, and the interactions between substances through chemical reactions to form different substances.
Physics – the natural and physical sciences that involve the study of matter and its motion through space and time, along with related concepts such as energy and force. More broadly, this is a general analysis of nature, undertaken to understand how the universe behaves.
Astronomy – the study of celestial bodies (such as stars, galaxies, planets, moons, asteroids, comets and nebulae), physics, chemistry and evolution of these objects, and phenomena originating outside the Earth’s atmosphere, including supernova explosions, gamma ray bursts, and cosmic microwave background radiation.
Earth sciences – an all-encompassing term that refers to any field of science related to the planet Earth. Earth sciences are the study of how the natural environment (the ecosphere or Earth system) works and how it evolved into its current state. This includes the study of the atmosphere, hydrosphere, lithosphere and biosphere.
