PRACBEE REVISION PROGRAM

We have started this video with weightage of the topics in JEE. Then we will jump into the Mind map of the chapter, so you know which topics and subtopics are covered in Oscillations chapter for IIT JEE - JEE Main and JEE Advanced, and how these are interlinked with each other. That helps you cover the entire chapter comprehensively and ensure you do not miss any single subtopic or concept from it.

Since the video has 3-4 questions from each of the 15 types of problems from Oscillations chapter, all from Past Year Questions of JEE Main, we are keeping 2 questions per type in the blog. We will add the list of the 15 problem types followed by 2 questions from each type.

We are going to systematically start with the weightage of the topic then go into the subtopics that need to be covered then go into more deeper points of what exactly there is in the syllabus using mind maps and ultimately come on to the 15 problem types.

Before we start this video there is a “do” and there is a “don't”. The “do” is do not watch this video like you are watching a movie but keep making notes, keep solving questions, pause the video and see how you can arrive on an answer and develop your approach while solving. The “don't” is that this video is not meant for a fresher student who has not just studied the chapter. We will not go into very basics but yes, I will tell you the concept wherever and whenever it is required.

Weightage:

Oscillations and SHM is one of the most important chapters, which has its application in other chapters as well. So, if you watch this video till end you'll be able to answer 1 or 2 questions that can be asked from this chapter in JEE Main across papers.

Syllabus:

Oscillations and periodic motion: time period, frequency, displacement as a function of time, periodic functions. Simple harmonic motion (S.H.M.) and its equation, phase, oscillations of a spring: restoring force and force constant, energy in S.H.M.: kinetic and potential energies, simple pendulum: derivation of expression for its time period.

If we look at the syllabus, in this chapter we have oscillation, periodic motion, then time period, calculation for simple harmonic motion, then what is the frequency, the displacement, displacement of the particle as a function of time, and then what is the periodic motion. Then simple harmonic motion and its equation phase, what do you mean by phase, what is initial phase constant, then the oscillation of a spring. If a spring is connected with a block, then what is the time period of the oscillation of the block, then the concept of restoring force, what is force constant, then the energy of a simple harmonic motion, kinetic energy, potential energy of the particle which is undergoing simple harmonic motion, the concept of simple pendulum, and the derivation of the expression for its time period. So, we are going to cover these 15 problem types and we have arranged these problem types as the way we teach in a regular class.

Mindmap of the chapter – Oscillations and SHM

We hope you enjoyed this blog as well as the video, in which we went into the details of different kinds of problems that can be formed from Oscillations chapter in JEE Main, and how to solve them.

In this program we sit with the student to understand their preparation till this point of time and based on that in step two we write a customized planner just for you to help you optimize your marks in JEE Mains exam based on whatever preparation you have done. In step three we sit with you 1:1 by a set of faculties aligned by Pracbee and help you implement the customized plan that we wrote for you.

Students have come to us with limited or decent preparation, and all have been able to score their marks to a large extent. Asesh using this program was able to improve his fortunes by a lot starting from 95% in J Mains means attempt 1 to getting selected for mechanical in IIT Madras. Ditya over a period of time was able to crack JEE Advance using this program.
