This article will examine what constitutes a natural science, the goals and methods of physics, and why physics is universally included under the umbrella of natural science.

If you’re short on time, here’s a quick answer: Yes, physics is considered one of the natural sciences, along with disciplines like biology, chemistry, and earth science. Physics focuses on understanding the natural world through scientific inquiry and experiments.

Defining the Natural Sciences

The natural sciences are a branch of science that focuses on the study of the natural world. They aim to understand and explain the phenomena, laws, and processes that occur in the physical and natural universe.

This field of study is characterized by its use of the scientific method, which involves observation, experimentation, and the formulation of theories and hypotheses.

Study of the Natural World

The natural sciences encompass various disciplines that investigate different aspects of the natural world. These disciplines include biology, chemistry, physics, and earth science. Each discipline focuses on specific areas of study but shares the common goal of understanding the natural processes and laws that govern our world.

Use the Scientific Method

The scientific method is a systematic approach used by scientists in the natural sciences. It involves making observations, formulating hypotheses, conducting experiments, analyzing data, and drawing conclusions.

This rigorous method ensures that scientific studies are conducted in a systematic and objective manner, allowing for the accurate interpretation of results.

Include Biology, Chemistry, Physics, Earth Science

Biology is the study of living organisms and their interactions with the environment. It explores topics such as genetics, evolution, ecology, and cellular biology. Chemistry focuses on the composition, structure, properties, and reactions of matter.

It plays a crucial role in understanding the chemical processes that occur in the natural world. Physics is the study of matter, energy, and the fundamental laws that govern the universe. It encompasses areas like mechanics, thermodynamics, electromagnetism, and quantum physics.

Earth science investigates the planet Earth, including its geology, atmosphere, hydrosphere, and biosphere.

May Overlap with Formal Sciences

While the natural sciences primarily focus on the study of the natural world, there can be some overlap with the formal sciences. The formal sciences, such as mathematics and logic, are concerned with abstract concepts and the development of formal systems.

However, these disciplines often intersect with the natural sciences, particularly in areas like mathematical modeling, statistical analysis, and theoretical physics. This collaboration between the natural and formal sciences allows for a deeper and more comprehensive understanding of the natural world.

Goals and Methods of Physics

Physics, as a natural science, encompasses a wide range of goals and methods that contribute to our understanding of the natural world. By examining nature’s universal laws, utilizing empirical evidence from experiments, and continually testing and refining theories, physics plays a crucial role in unraveling the mysteries of the universe.

Seeks to Understand Nature’s Universal Laws

At its core, physics strives to understand the fundamental laws that govern the behavior of the natural world. These laws, such as Newton’s laws of motion or Einstein’s theory of relativity, provide a framework for explaining the behavior of objects and phenomena.

By uncovering these universal laws, physicists can gain insights into the workings of the universe on both the macroscopic and microscopic scales.

Uses Empirical Evidence from Experiments

One of the key methods employed by physicists is the use of empirical evidence obtained from experiments. By designing and conducting experiments, physicists can collect data that helps them validate or refute existing theories.

Through careful observation and measurement, they can gather evidence to support their hypotheses and draw reliable conclusions about the natural world. This reliance on empirical evidence ensures that the field of physics remains grounded in observable and measurable phenomena.

Tests and Refines Theories About the Natural World

Physics is a dynamic field that constantly tests and refines theories about the natural world. Through experimentation and theoretical modeling, physicists strive to develop accurate and predictive explanations for various phenomena.

They construct mathematical models and conduct simulations to simulate real-world scenarios, allowing them to make predictions and test the validity of their theories. This iterative process of testing and refinement is crucial for advancing our understanding of the natural world and pushing the boundaries of scientific knowledge.

Physics Aligns With Principles of Natural Science

When discussing the classification of sciences, it becomes clear that physics is indeed a natural science. This is due to the fact that physics aligns with several key principles of natural science, which include observing and classifying natural phenomena, using scientific processes like induction and deduction, and producing widely accepted theories about the natural world.

Observes and Classifies Natural Phenomena

Physics is deeply rooted in observation and classification of natural phenomena. Physicists study the behavior of matter and energy, exploring everything from the motion of celestial bodies to the properties of subatomic particles.

By carefully observing these phenomena, physicists are able to identify patterns, formulate hypotheses, and ultimately develop theories to explain the underlying principles at work.

For example, in the field of astrophysics, scientists observe the movements and interactions of celestial objects such as stars, planets, and galaxies. Through meticulous observation and data collection, they are able to classify these objects based on their characteristics and behavior.

This classification allows for a better understanding of the universe and its natural processes.

Uses Scientific Processes Like Induction and Deduction

Physics relies on scientific processes such as induction and deduction to formulate theories and make predictions. Induction involves making generalizations based on specific observations, while deduction involves drawing logical conclusions from given premises.

Physicists use these processes to analyze experimental data, develop mathematical models, and test hypotheses. By employing rigorous methods of inquiry, physicists are able to uncover the fundamental laws that govern the behavior of the natural world.

For instance, Isaac Newton’s laws of motion, formulated through a combination of observation, experimentation, and mathematical reasoning, are still widely used today to explain the motion of objects on Earth and in space.

These laws were derived through a process of induction and deduction, making them a testament to the scientific nature of physics.

Has Produced Widely Accepted Theories About the Natural World

Physics has a rich history of producing widely accepted theories that provide explanations for various natural phenomena. These theories have stood the test of time and continue to shape our understanding of the universe.

One such example is Albert Einstein’s theory of relativity, which revolutionized our understanding of space, time, and gravity. This theory has been rigorously tested and validated through experiments and observations, earning it widespread acceptance among the scientific community.

Another groundbreaking theory is quantum mechanics, which describes the behavior of particles on a subatomic level. This theory has been instrumental in advancing fields such as electronics, telecommunications, and nanotechnology.

Contrasting Physics and Other Sciences

More Empirical Than Mathematics or Computer Science

Physics, as a natural science, is distinguished from disciplines like mathematics and computer science by its emphasis on empirical observation and experimentation. While mathematics relies on abstract concepts and logical reasoning to derive conclusions, physics seeks to understand the natural world through the collection and analysis of data.

This empirical approach allows physicists to make predictions and test their theories against real-world phenomena.

For example, when studying motion, physicists gather data on the position, velocity, and acceleration of objects, and use this information to develop mathematical models that describe the behavior of these objects.

By comparing their models to experimental results, physicists can refine their theories and gain a deeper understanding of the underlying principles at play.

More Fundamental Than Applied Sciences Like Engineering

Physics is often considered more fundamental than applied sciences like engineering. While engineering applies scientific principles to design and build practical solutions, physics seeks to uncover the fundamental laws and principles that govern the behavior of the natural world.

Engineers rely on the foundational knowledge provided by physics to develop technologies and solve real-world problems. For example, understanding the laws of thermodynamics and electromagnetism is crucial for designing efficient engines or developing electrical systems.

Physics provides the theoretical framework that underpins these practical applications.

Distinct From Social Sciences Like Psychology

Physics also stands apart from social sciences like psychology. While psychology studies human behavior and the mind, physics focuses on understanding the fundamental forces and particles that make up the universe.

Physics seeks to explain phenomena such as gravity, electromagnetism, and quantum mechanics, which are fundamental to the functioning of the natural world. On the other hand, psychology explores the complexities of human cognition, behavior, and emotions.

Both fields play important roles in advancing knowledge, but they approach their respective subjects from different angles.


While physics is a highly theoretical and quantitative science, its ultimate mission is to describe the fundamentals of the natural world. Physics uses scientific methods to formulate theories validated by experiments and observations of nature.

For these reasons, physics solidly sits within the domain of the natural sciences, alongside similar disciplines like chemistry and biology that also seek fundamental truths about our natural universe.
