Beyond Textbooks: Practical Applications of Physical Science in Our Daily Lives


Physical Science is the branch of science that explores the fundamental principles governing the physical aspects of the universe. It involves the study of non-living systems including matter, energy, motion, forces and their interactions. The two main subjects under physical science are Physical Science and chemistry.

It has been instrumental in driving the technological advances that have shaped modern society. From electricity and magnetism, which power our devices, to semiconductors and microprocessors, which underpin our digital age, these breakthroughs stem from a deep understanding of physical principles.

Understanding physical science principles allows engineers to design and create innovative solutions to real-world problems. Engineers rely on the laws of Physical Science and chemistry to construct buildings, bridges, transportation systems, and cutting-edge technologies that improve the quality of our lives.

It helps us understand natural phenomena, such as weather patterns, earthquakes and celestial events. By studying the principles of thermodynamics, fluid mechanics and electromagnetism, we gain insight into the forces that shape our environment.

An understanding of physical science is critical in the search for sustainable energy solutions. This enables us to explore renewable energy sources such as solar, wind and hydropower and address serious environmental challenges.
