| Introduction to Physics | In the 19th century, physical sciences were divided into five distinct disciplines: physics, chemistry, astronomy, geology, and meteorology. The most fundamental of these is physics. In physics, we study matter, energy, and their interactions. The laws and principles of physics help us understand nature. |
| Physics in Science | Physics is the foundation of all sciences. To study biology, chemistry, or any other natural science, a firm understanding of the principles of physics is essential. Examples include understanding blood flow in biology and atomic interactions in chemistry. |
| Physics and Technology | Technology is deeply rooted in physics principles. Everyday devices such as computers, smartphones, and the internet rely on physics. Advanced technologies like rockets, magnetic levitation trains, and medical innovations are based on physics. |
| Branches of Physics | Major branches of physics include Mechanics, Optics, Oscillation and Waves, Thermodynamics, Electromagnetism, Astrophysics, Quantum Physics, Atomic Physics, and Nuclear Physics. |
| Did You Know? | The cubit was the measurement unit used by Egyptians to build the pyramids. It is the distance from your elbow to the tip of your middle finger when your arm is extended. |
| The Role of Mathematics in Physics | Physics has a strong connection with mathematics. Mathematics is used as a tool to understand nature and the physical world. Learning physics requires a solid understanding of mathematical concepts. |
