This text book is primarily intended for students who are preparing for the entrance tests of IIT-JEE/NEET/AIIMS and other esteemed colleges in same fields. This text is equally useful to the students preparing for their school exams.Main Features of the Book-1. Every concept is given in student friendly language with various solved problems and checkpoint questions. The solution is provided with problem solving approach and discussion.2. Special attention is given to all tricky topics (like- dimensional problems with integration sign, conversion of units, measurement of large distances by parallax method, combination of errors, applications of vectors in physics with problem-solving approach, constrained relations, block over block friction problems, graphical problems, motion under negative acceleration, juggling problems, relative velocity, projectile motion, condition for a projectile to retrace its path, radius of curvature at any point on the trajectory of projectile, projectile motion on inclined plane and stairway, relative velocity, river boat/man problems, rain man problems, motion of many particles, with same speed, towards each other in a plane, motion of two particles, with different speed, towards each other in a plane, constrained relations and block over block friction problems), so that student can easily solve them with fun.3.To test the understanding level of students, multiple choice questions, conceptual questions, practice problems with previous years JEE Main and Advanced problems are provided at the end of the whole discussion. Number of dots indicates level of problem difficulty. Straightforward problems (basic level) are indicated by single dot (●), intermediate problems (JEE mains/NEET level) are indicated by double dots (●●), whereas challenging problems (advanced level) are indicated by thee dots (●●●). Answer keys with hints and solutions are provided at the end of the chapter.
