"Classical Mechanics" is a fundamental subject in physics that deals with the motion of macroscopic objects under the influence of forces. The book by Gupta, Kumar, and Sharma is presumably a textbook aimed at undergraduate or postgraduate students in physics or engineering, covering the principles of classical mechanics.
