What Do You Learn In Physical Science?

Physical science encompasses a broad range of topics that help explain the physical world around us. From physics and chemistry to Earth science and astronomy, physical science courses provide foundational knowledge about matter, energy, motion, forces, and much more.

If you’re short on time, here’s a quick answer to your question: Physical science teaches about physics, chemistry, astronomy, Earth science, and how the physical world works through an examination of matter, forces, motion, and energy.

In this article, we’ll take a deeper look at the key topics covered in a typical high school or introductory college physical science course.



In the study of physics, one of the fundamental concepts covered is motion. Students learn about the different types of motion, such as linear, circular, and projectile motion. They explore concepts like speed, velocity, and acceleration, and learn how to calculate them using mathematical formulas.

Through experiments and observations, students gain an understanding of the laws of motion formulated by Sir Isaac Newton.


Another important topic in physics is forces. Students learn about the different types of forces, including gravitational, frictional, and magnetic forces. They explore how forces can cause objects to move, change direction, or deform.

Students also learn about Newton’s laws of motion, which explain how forces affect the motion of objects. They learn how to calculate forces using mathematical formulas and understand concepts like balanced and unbalanced forces.


The study of energy is a significant part of physical science. Students learn about different forms of energy, such as kinetic, potential, thermal, and electrical energy. They explore the principle of conservation of energy and how energy can be transferred or transformed from one form to another.

Students also learn about energy sources, including renewable and non-renewable sources, and the impact of energy consumption on the environment.

Waves and Light

Physics also covers the study of waves and light. Students learn about the properties of waves, such as amplitude, frequency, wavelength, and speed. They explore different types of waves, including sound waves and electromagnetic waves.

Students also delve into the behavior of light, including reflection, refraction, and dispersion. They learn about the nature of light and its interaction with matter, leading to understanding concepts like color, optics, and the functioning of lenses and mirrors.


Properties of Matter

In the study of physical science, chemistry is a fundamental branch that focuses on the properties of matter. Matter is anything that has mass and occupies space. This subfield of physical science explores the different characteristics and behaviors of matter, such as its physical and chemical properties.

Students learn about concepts like density, solubility, and conductivity. They investigate how different substances interact with each other and how these interactions can be measured and analyzed.

Atoms and Elements

Another important aspect of chemistry in physical science is the study of atoms and elements. Atoms are the building blocks of matter, and elements are substances made up of only one type of atom. In this subfield, students learn about the periodic table of elements, which organizes all known elements based on their atomic number and properties.

They explore the structure of atoms, including protons, neutrons, and electrons, and how these components contribute to the behavior of different elements.

Chemical Reactions

Chemical reactions are a key concept in chemistry. Students learn how substances can undergo changes, resulting in the formation of new substances with different properties. They study the different types of chemical reactions, such as synthesis, decomposition, combustion, and oxidation-reduction.

Through experiments and analysis, students gain a deeper understanding of the factors that affect the rate of reactions, including temperature, concentration, and catalysts. They also explore stoichiometry, which involves the calculation of the quantities of substances involved in a chemical reaction.

Acids and Bases

The study of acids and bases is another important topic covered in physical science chemistry. Students learn about the pH scale, which measures the acidity or alkalinity of a substance. They explore the properties and behaviors of acids and bases, including their reactions with each other and with other substances.

Students also learn about indicators and titration, which are methods used to determine the concentration of acids and bases in a solution. Understanding acids and bases is crucial in various fields, such as medicine, environmental science, and industry.

Earth Science

In the field of physical science, one of the key areas of study is Earth Science. This branch of science focuses on understanding the various processes and phenomena that occur on our planet. By delving into the study of Earth Science, students gain knowledge about different aspects of our planet, including geology, meteorology, oceanography, and astronomy.


Geology is the study of the Earth’s solid materials, such as rocks, minerals, and the processes that shape and change the Earth’s surface. It involves examining the composition, structure, and history of the Earth’s crust, as well as the forces that have shaped it over time.

Geologists study everything from the formation of mountains and volcanoes to the movement of tectonic plates and the creation of fossils.


Meteorology is the study of the Earth’s atmosphere and the processes that drive weather and climate. Meteorologists analyze weather patterns, atmospheric conditions, and natural phenomena like hurricanes and tornadoes.

By studying meteorology, students learn about important concepts such as air pressure, temperature, humidity, and the formation of clouds and precipitation.


Oceanography is the scientific study of the Earth’s oceans, including their physical and chemical properties, as well as the organisms that inhabit them. Oceanographers explore topics such as ocean currents, tides, waves, and the distribution of marine life.

They also investigate the impacts of human activities on ocean ecosystems and the importance of preserving these vital natural resources.


Astronomy is the study of celestial objects, such as stars, planets, galaxies, and other phenomena in outer space. By studying astronomy, students gain knowledge about the universe, its origins, and its evolution.

Astronomers use telescopes and other instruments to observe and analyze celestial bodies, and they explore fascinating topics such as the Big Bang theory, black holes, and the search for extraterrestrial life.

Earth Science encompasses a wide range of fascinating subjects that help us understand the Earth and the universe we live in. By studying geology, meteorology, oceanography, and astronomy, students gain a deeper appreciation for the natural world and how it functions.

Whether it’s exploring the formation of mountains, predicting weather patterns, investigating ocean ecosystems, or unraveling the mysteries of outer space, Earth Science offers a wealth of knowledge that continues to inspire and awe.


In summary, physical science provides a broad introduction to topics in physics, chemistry, astronomy, and Earth science. Students gain foundational knowledge about the physical world through an examination of matter, motion, forces, energy, space, and much more.

While an introductory physical science course only scratches the surface of these vast fields, it equips students with core concepts, problem-solving skills, and scientific literacy to build upon in further science studies.
