Physical science, commonly known as physics, plays a vital role in aviation and aerospace technology. Many of the systems and operations found in aircraft—from engines and propulsion systems to flight performance and aerodynamics—are governed by the basic laws of physics. Understanding these principles helps explain how aircraft generate thrust, overcome drag, and maintain controlled flight.
Physics is the branch of science that studies the behavior and properties of matter and energy. In aviation, these principles help describe how forces act on aircraft structures, how energy is converted into motion, and how pressure, temperature, and airflow influence aircraft performance. By applying physical laws, engineers and technicians can analyze and predict how aircraft systems operate under different conditions.
Aviation maintenance technicians must understand the fundamental concepts of physics in order to properly maintain aircraft systems and interpret technical information. Concepts such as force, work, power, motion, heat, and fluid mechanics form the foundation for understanding aircraft engines, hydraulic systems, and aerodynamic behavior.
The following series introduces the fundamental physics concepts that apply to aviation, along with the basic principles of flight. These topics include matter and energy, mechanical forces, motion, pressure and gas laws, and the aerodynamic principles that allow both fixed-wing aircraft and helicopters to fly.
