Mechanics is one of the basic units in the preparation of IIT JEE, AIEEE, and other engineering examinations. A beginner mostly starts with this unit in Physics. Mechanics is not only a lengthy portion in Physics but it forms the basis of entire Physics. It will not be an exaggeration to say that it is the most important unit in Physics from the point of view of preparation of IIT JEE, AIEEE, and other engineering examinations.
Mechanics begins with Kinematics which deals with the motion of a particle in one and two dimensions. This portion along with the next topic Newton’s Laws of Motion fetches 2-3 questions in the IIT JEE, AIEEE, and other engineering examinations every year. Work Power and Energy, Conservation of Momentum and Collision, Centre of Mass, and Rotational Dynamics becomes a very important portion from the viewpoint of Examination. These topics together form the heart of Mechanics. IIT JEE, AIEEE and other engineering examination fetch about 15 % of the total Physics questions. Those who get good IIT JEE rank always do well in this section. Simple harmonic Motion and Hydrostatics are also important as this fetches question in the IIT JEE, AIEEE and other engineering examination almost every year.
It is a point to note that this unit of Mechanics can be easily dealt with the proper understanding of the concept which is strengthened with the practice of numerical problems.
Following topics are covered under mechanics:-
2. Laws of Motion
3. Work Energy and Power
4. Rigid Body Dynamics
6. Fluid Mechanics
7. Thermal Physics
