Physics Concepts

Physics is one of those subjects that needs to be understood rather than memorized. In general, a large number of students tend to forget the formulas or either their application. Physics consists of complex formulas and it is very important for students to understand the reasoning behind the formulas if they want to excel in this subject.

Our “Physics Concepts'' section has been meticulously curated in a way that covers everything from basic concepts like the law of motion to complex topics like thermodynamics along with their formulas, definitions, faqs and correct application with examples.
