Physics helps us understand how our world works. It studies a very wide range of objects, from the very small (through quantum principles) to the entire universe (through general relativity).

The subject not only covers the objects’ behavior under a specific environment, but also the origin and nature of gravitational, electromagnetic, and nuclear forces. It aims to formulate comprehensive principles that explain all such contrasting phenomena.

It also helps us develop quantitative and analytic skills required for evaluating data and solving complex problems in sciences, medicine, engineering, finance, and economics.

However, there are many aspects that scare of students.

For example, physics include a lot of math topics like complex numbers, differential equations, statistics and probability, and some special functions, which makes it difficult for students to build on basic concept. Then, there is solid-state physics, statistical mechanics, quantum mechanics, high-energy physics, etc., that add to the challenging concepts.
