'knowledge of nature', from φύσις phýsis 'nature') is the natural science that studies matter, its motion and behavior through space and time, and the related entities of energy and force. Physics is one of the most fundamental scientific disciplines, and its main goal is to understand how the universe behaves. An equation (e.g., f = m a) is called a "law" when there are clear empirical results that substantiate it. For example, theoretical physicists use mathematics and numerical analysis and statistics and probability and computer software in their work.
Physics is very important in the development of new Modern physics connects ideas about the four laws of Natural philosophy started in Greece around 650 BC when Physics became a separate field of study after the As scientists researched particles, they discovered what classical mechanics could not explain. In this way, theoretical physicists often use tools from These two main activities in physics, data collection, theory production and testing, use many different skills.

First law of thermodynamics gives us the relation them by the following equation (ΔU = Quantum mechanics is the study of particle at the atomic level taking into consideration the atomic model. Let's think about what physics is and what topics are covered in an introductory physics course. It is also called quantum physics or quantum theory.Mechanics is the part of physics that explains how things move and quantum is the Latin word for 'how much' . Sciences also tend to become more quantitative with time as they become more highly developed, and physics is one of the oldest sciences. Physics is a branch of science.It is one of the most fundamental scientific disciplines.The main goal of physics is to explain how things move in space and time and understand how the universe behaves. For example, condensed matter physics and nuclear physics benefit from the ability to perform experiments. That is, many of the observations in physics may be represented in the form of numerical measurements. It includes subtopics Path integral formulation, scattering theory, Schrödinger equation, quantum field theory, quantum statistical mechanics. The data in some subfields of physics is amenable to experiment. One of the major goals of physics is making theories that apply to everything in the universe. The word physics comes from the Greek word ἡ φύσις, meaning "nature". Theoretical physics often uses quantitative approaches to develop the theories that attempt to explain the data.
