Physics – physical science that studies matter and its motion through space-time, and related concepts such as energy and force. Acoustics – study of mechanical waves in solids, liquids, and gases (such as vibration and sound) Agrophysics – study of physics applied to agroecosystems. Soil physics – study of soil physical properties and ...
Physics – natural and physical science could involve the study of matter [4] and its motion through space and time, along with related concepts such as energy and force. [5] More broadly, it is the general analysis of nature, conducted in order to understand how the universe behaves. [a] [6] [7] Branches of physics

Particle physics or high-energy physics is the study of fundamental particles and forces that constitute matter and radiation. The field also studies combinations of elementary particles up to the scale of protons and neutrons , while the study of combination of protons and neutrons is called nuclear physics .
The strong interaction, or strong nuclear force, is the most complicated interaction, mainly because of the way it varies with distance. The nuclear force is powerfully attractive between nucleons at distances of about 1 femtometre (fm, or 10 −15 metres), but it rapidly decreases to insignificance at distances beyond about 2.5 fm. At ...
Asymptotic freedom means that the strong force becomes weaker, as the energy scale increases. The strong force overpowers the electrostatic repulsion of protons and quarks in nuclei and hadrons respectively, at their respective scales. While quarks are bound in hadrons by the fundamental strong interaction, which is mediated by gluons, nucleons ...
Thermodynamics studies the effects of changes in temperature, pressure, and volume on physical systems on the macroscopic scale, and the transfer of energy as heat. [ 2 ] [ 3 ] Historically, thermodynamics developed out of the desire to increase the efficiency of early steam engines .
He then defines four principles that characterize the four basic forces in nature: electromagnetism, gravity, the strong force and the weak force. ... What a reader gets in "Fundamentals" is the native language of physics—mathematics—precisely translated by someone who has spent a lifetime (about a billion thoughts!) on these forces that ...
