What Is the Difference between Physics and Physical Science

Quite often, we confuse different fields of studies with each other, either because they sound similar or we assume that both the topics provide the same information. Similar is the case with physics and physical sciences.

What Is Physical Sciences?

The world is widely divided into two types of substances, one is organic and the other is inorganic. Organic substances are the ones that form the core of biological sciences. Physical sciences are concerned with the study of the inorganic world.

Physical science is not like a specific subject, it is subdivided into different fields, which are then subdivided into even smaller fields of studies. The four main divisions that come under physical sciences are earth sciences, chemistry, astronomy, and physics. Yes, you saw it. Physics is the subdivision of physical sciences, not physical science itself.

Here is a little overview of the branches of physical sciences:

1) Astronomy:

Astronomy is a very interesting branch of physical sciences. It deals with the study of celestial objects and unearthly phenomena; the ones that originate from beyond the Earth’s surface. All these magical entities you see in movies such as asteroids and comets are all studied under this very branch of physical sciences.

2) Chemistry:

Everyone is familiar with chemistry. It is that one subject because of which most students seek assignment help online, as it is generally known to be very challenging for students. Chemistry is basically the study of chemicals, their compositions, and how they react in a chemical reaction when they are creating new substances. It deals with the study of intracellular, intercellular, and intramolecular forces, etc.

3) Earth Sciences:

Earth science is a very broad term. As the name itself suggests, this particular field of study is related to the study of the earth. It generally deals with how the environment works and how it has changed over time to become what it is today. The study of the biosphere and atmosphere all come under Earth Sciences. For instance, if you search marketing assignment help UK-based, you will instantly be shown with results of marketing and business websites. In the same way, if you search about earth sciences, you will get more variety in your search results. You will get results in geography, meteorology, oceanography, etc. which signifies how earth sciences is a wide-ranging type of science.

4) Physics:

This is where physics comes into existence. It is also like chemistry and astronomy, a type of physical science. In simple words, physics is the study of the relationship between matter and energy. It helps understand how the world behaves by using scientific theories and formulas. Physics is taught in high schools and it gets more advanced over time. As we move forward in our academic life, all subjects get more complicated as we are getting a more in-depth knowledge of the subject, students are more likely to seek assignment help online because it is a much more difficult level of study.

The Basic Principles of Physics:

Physics is a fundamental science based on many laws and theories many past and present scientists have worked to build. Here are a few principles on which physics is based.

-Newton’s laws of motion.

-Gravity, Theories of Gravity.

-Relationship of Energy and Work

-Conservation of Energy and Momentum.

Difference between Physical Sciences and Physics:


  • Physics is the study of the science of energy.
  • It deals with the study of the physical universe without dealing with chemistry, earth sciences, or meteorology.
  • It also focuses on the motion of an object and its movement through time and space.
  • The study of the basis of physics helps us better understand the basis of chemistry and other forms of studies too.

Physical Sciences:

  • Physical sciences is a pretty broad term that deals with the study of non-living systems.
  • Chemistry, Earth Sciences, Astronomy, and Physics, are all the main branches of physical sciences.
  • Its main focus is the study of the inorganic world, in any form, be it chemistry, astronomy, or physics.
  • The study of physical sciences gives us a broader overview of how the world evolves, changes, and gets affected by the non-living portion of the planet.

Final Thoughts:

You can never put boundaries on any type of science. Many are inter-linked, for example, Different chemistry phenomena can be explained using principles of Physics. Hence, all sciences work together in harmony to help us better understand how the mysteries of the world and universe unravel.
