General things about physics

How Things Work uses familiar objects to introduce basic physics concepts, demonstrating the excitement and relevance to professionals in a variety of technical fields. Because its structure is defined by real-life examples, this book explores concepts as they're needed and then revisits them later on when they reappear in other objects. It integrates case studies throughout the chapters to easily convey an understanding and appreciation for physics. For example, discussions of skating, falling balls, and bumper cars are included to explain the Laws of Motion. Air conditioners and automobiles are used to explore thermodynamics. Engineers, architects, and professionals in other technical fields will benefit from the material that connects science to our everyday world.

The Role of physics in science

In a broader sense, physics can be seen as the most fundamental of the natural sciences. Chemistry, for example, can be viewed as a complex application of physics, as it focuses on the interaction of energy and matter in chemical systems. We also know that biology is, at its heart, an application of chemical properties in living things, which means that it is also, ultimately, ruled by the physical laws

Use of physics in our life

In present time everythings is possible to physics as: air condition, computers, satelites, television...etc.
physics deal with matter on scales ranging from sub-atomic particles(i.e. the particles that make up the atom and the particles that make up those particles) to stars and even entire galaxies.
As an experimental science, physics utilizes the scientific method to formulate and test hypotheses that are based on observation of the natural world. The goal of physics is to use the results of these experiments to formulate scientific laws, usually expressed in the language of mathematics, which can then be used to predict other phenomena.
