Physics > Introduction: Physics and Matter

Matter – this is one of the main concepts in physics… Read the definition, concept of matter in physics, structure, history of the term, composition, explanation of physics.

Physics – study of the behavior of the universe.

Learning challenge

  • Apply physics to describe the mechanisms of everyday life.

Key points

  • Physics is a natural science focused on the study of matter and its movement through space and time, along with related concepts like force and energy.
  • That which has mass and volume is taken as matter.
  • Scientific laws and theories reveal the general truths of nature. These are the rules by which all natural processes exist.

Term

The scientific method is the discovery of knowledge about the world based on hypotheses, their empirical testing and the development of theories that can best explain the data obtained.

Physics is a natural science that studies matter and its movement through space and time, as well as related concepts (energy and force). More broadly, this is an attempt to understand the behavior of the Universe through the study of nature.

In order to reveal the main principles that determine light and matter, as well as to reveal the consequences, physics applies the scientific method. There is an opinion that the Universe is ordered, which means it follows specific laws, some of which can be investigated. Moreover, these laws can be used to predict the universe’s future. But for this you need to get complete information about light and matter.

What is the definition of matter in physics? Matter is understood as everything that has volume and mass. Among the concepts, you can find many theories and laws that try to explain matter itself and its movement. For example, you can take the law of conservation of mass, which says that mass cannot be created or destroyed. It is clear that subsequent analyzes and experiments will take this law into account in order to decipher natural phenomena.

Physics is set up to describe everything around it. This begins with the movement of particles invisible to us and the movement of both humans and large formations. In fact, literally everything can be described in physics.

For example, a smartphone. Physics is able to explain how electricity functions in different circuits of a device. This allows engineers to select the right materials and follow a clear structure. What about GPS? The laws of physics describe the relationship between the speed of an object, the distance it travels and the required time. The GPS in your car or phone uses physical equations to calculate the time it takes to get from one point to another. So knowledge of physics strongly influences the development of technology.
