●In this physical world, while explaining physics give its scope, How physics is related to other branch of science, society and technology
● Explain different types of forces which exists in nature? Also explain various laws of conservation
PLS TELL answer of the question

Answer:
1)Physics is also called "the fundamental science" because the subject of study of all branches of natural science like chemistry, astronomy, geology, and biology are constrained by laws of physics, similar to how chemistry is often called the central science because of its role in linking the physical sciences.
2)Exact conservation laws include conservation of energy, conservation of linear momentum, conservation of angular momentum, and conservation of electric charge. There are also many approximate conservation laws, which apply to such quantities as mass, parity, lepton number, baryon number, strangeness, hypercharge, etc.
Conservation law, also called law of conservation, in physics, several principles that state that certain physical properties (i.e., measurable quantities) do not change in the course of time within an isolated physical system. ... In an isolated system the sum of all forms of energy therefore remains constant.
