Physics is an incredibly important science. It intersects across multiple fields and is one of the most widely used concentrations on Earth.

While it is closely related to both biology and chemistry, the science differs because it covers mechanics, heat, light, radiation, electricity, magnetism, sound, and the structure of atoms.

The discipline is defined as the branch of science concerned with the nature and properties of both matter and energy.

This article will break down that physics definition, as well as its larger themes, to help you understand exactly what it is and why it’s so important.


Answering Questions, Both Big and Small

Physics, at its core, asks questions about the fundamental forces that guide the universe. Delving into gigantic mysteries is one of the field’s defining traits, and what helps it stand apart from other sciences.

For instance, physicists seek out questions like “how did the universe start?” or “what are the basic building blocks of matter?”

For that reason, physics typically pertains to the much larger parts of our world.

However, when asking “what is physics?” it is important to note that science is not purely theoretical. Though a lot of the field sits in the theoretical realm, much of it is about much more concrete concepts.

The science is used throughout many different parts of human activity and has helped researchers solve a range of tough problems over the years. It has played a key role in the development of sustainable energy, computer games, and sports equipment. It also aids new cancer research and helps scientists understand earthquakes.

For that reason, physics is a unique science that exists in two different sectors. One part is all about trying to understand the broader universe, while the other centers on directly applying science to our world.

In that way, it is the science of nature that deals with the laws and properties of matter, as well as the forces which act upon them.


Physics in Relation to Math, Technology and Energy

Math, which helps scientists make sense of our world, is a vital part of physics. This connection runs through the entire field and that is key to understand when attempting to define the science.

Most natural properties can be understood through relatively simple mathematical relationships. Physics seeks to find and study such relationships through a mix of models, observations, and experiments.

Physics connects to technology as well.

As our world becomes more advanced, so does science. Physics is a prime example of that because the field readily incorporates both new-age computers and programming languages to help answer or solve some of life’s biggest questions. Such technology is particularly useful when trying to find the solution to scientific problems or modelling advanced processes.

Energy is also a huge part of modern physics.

Not only do physicists work to create and understand energy, but physics is a field where matter and energy are studied both separately and in combination with one another.


The Overlap with Other Sciences

As with so many different sciences, physics works in conjunction with other fields. The branch needs scientific methods to understand the natural world, and that cannot be done without mixing different disciplines together.

To understand the fundamental principles of the universe, physics utilizes many workings from the other natural sciences. As a result of that overlap, phenomena studied in physics (the conservation of energy for example) are common to all material systems. That then leads many to refer to the ways physics applies to energy as the “laws of physics.”

Physics is also called the “fundamental science.”

This does not mean it is more important than other fields, but that many natural sciences work within its systems. Biology, chemistry, geology, material science, medicine, and engineering adhere to the laws of physics.

For instance, chemists need to reference theories that come from quantum mechanics, thermodynamics, and electromagnetism in order to produce and understand certain chemical compounds.

In addition, engineering has ties to the science through the application of electromagnetism.

Those connections are why physics is so important in the construction and evolution of modern society. It is not just a field of study, it is used in common systems and helps build a range of vital items, including electronic equipment, barometers, lasers, and nuclear weaponry.


The Properties of Matter and Energy

Understanding basic physics can seem intimidating, but it is a breeze once you have a little bit of background information.

This article covers everything you need to know about the science, and gives a thorough understanding about how it connects to the larger world.

All sciences are unique, but they are also similar. Now you know what makes physics special, as well as what makes it similar to other branches.
