Engineering is not considered a physical science. While engineering heavily relies on principles from physical sciences like physics, chemistry, and mathematics, it's classified as an applied science. Here's why:

* Physical sciences focus on understanding the natural world. They aim to discover fundamental laws and principles that govern the universe.

* Engineering applies scientific knowledge to solve practical problems and create solutions. Engineers use scientific principles to design, build, and improve systems, structures, and devices.

Think of it this way:

* A physicist might study the laws of motion and gravity.

* An engineer would use those laws to design a bridge or a rocket.

In essence, engineering uses the knowledge from physical sciences as a tool to achieve specific goals. It's the application of scientific principles, not the discovery of new ones.
