Physics is one of the important branches of science. Physics help us in understanding everyday activities. These activities can be put into question and answering questions like why things fall down, why and how things float on water and sink into the water, what makes us walk easily on roads, why it is important to have sun and moon, etc.
From the above-mentioned examples, it is quite clear that physics mainly concentrates in explaining the behaviour of the universe, matter, force, and their effects. Physics has helped in many inventions and in developing new technologies. Physics as a subject is further divided into branches and these branches are further divided into sub-topics. All these concepts of physics have major questions and these questions include properties, principles, definitions, types and examples.
