[00:00:00]Ok. So in this particular video section we are going to talk about short notes of classical mechanics. Let us see about the review of revision, what are these short notes, meaning you will get content in it. Let's discuss a little about it. And if after seeing this content you feel that you should purchase these short notes of Classical Mechanics then you can contact me on this particular Telegram ID. The simple ID is @NET meaning net 441. If you search on this, you can say that you will get all the information regarding notes there.

[00:00:38]So what have we covered in short notes in this note section. In that we saw the chapter on STR, Legion, Small Oscillation, Can's Transformation, Generating Function, Face Respect, Rejectory Center of Force, Motion and Rigid Body Dynamics, which means that all the topics which are in classical mechanics are asked in our net gate tips.

[00:01:00]Regarding all of them, summary and short notes will be available to you. So let us look at them one by one.

[00:01:05]Ok? So let's start with STR first. So in STR you will get to see all the important topics related to it. Like there is Lawrence transformation, inverse Lawrence transmission has happened. Then you saw this thing about velocity transmission is also included here. Inverse velocity transmission properties are achieved.

[00:01:26]Ok? Then after this some concentration of STR length contraction occurred.

[00:01:33]After this, the topic of time dilation is also included here. Then there was also the Railpastic Dynamics. In this way, regarding STR, all the important summary and formulas that you will need for solving the problems are included in it.

[00:01:51]Ok? Like there was a doper effect.

[00:01:53]This was also discussed here and in the last STR topic, you were also told about invariant quantities and what they are. So this is about STR. Next comes the topic of lager. Leg engines have all these starting points, from the basics to how many degrees of freedom each one has. What are the constraints? Isn't it? How to find the degrees of freedom of a rigid body.

[00:02:15]And regarding this, I have also included some notes here about the degrees of freedom if the disc is moving or rolling.

[00:02:23]Then here's what the Legion is all about.

[00:02:25]Regarding that, whatever the general momentum will be, there will be a variational principle about it. Isn't it? Leggen equation of motion was also discussed here. And then after this there is general generalized force, here it is also written about gas transformation kinetic energy of the different coordinate system potential energy.

[00:02:44]Then they have included the dynamics of the if the Lagrangian is given then if the equation of motion comes then what kind of dynamics will be there here, it is also written here about the potential energy for the definite system.

[00:03:00]This is it and then after this the leg chain is written here regarding some standard form. The Lagrange of this simple pendulum has been written here, it is a direct spring pendulum, it is a mass pulley system, and after this, information about cyclic coordinates has also been included here and the legion of the particle moving in a conical right, then the direct legion of these different types of systems has also been written regarding them so that you can recall the things, then information about the time period has also been written if motion is also taking place along with oscillation, and information about the double pendulum has also been written here. All the standards of the base block system are included here. So you can directly rev the engine here. Then came the spring mass regarding the system. Isn't it? Isn't it? With this, small oscillations begin. So in this, how can we find out small oscillations like normal Morse etc. and these are some systems. Regarding these, we need direct potential energy and kinetic energy. After that we have also solved them. So regarding that I have told you about the frequency of normal Morse.

[00:04:07]Then after this the conservations are lost. In which you will know which component will be conserved. Isn't it? Whether it's momentum, angular momentum, it's energy.

[00:04:19]So this has also been included here.

[00:04:21]So who will own all this? Of small oscillations. Then after this small oscillation we have our Hamiltonian. The Hamiltonian has everything covered. The equation of motion is done.

[00:04:33]Equations of motion in Poisson bracket form. Isn't it? Then it is written how to make Hamiltonian from Legion. After this, if there are coordinates of different types, then you have given the legion, then you can write the Hamiltonian in this way.

[00:04:45]Poison brackets have been explained.

[00:04:46]These are some of the tricks included in it.

[00:04:49]And then there are some properties of the Poisson bracket.

[00:04:51]These direct results were asked in previous years. So it has been included here. Ok? So all these things happened. Then after this we come to our transformation. So these are all the properties. and regarding canonical transforms.

[00:05:03]After that generating function is done.

[00:05:07]These are four types of generating functions.

[00:05:08]These are the questions regarding this. And then our phase space becomes exact.

[00:05:13]Ok? So in this, the fuzz space trajectory of standard cases has also been discussed here. Who is what and with respect to this you have got direct result in the question, so with respect to that only, like if the particle is moving in some familiar potential, then in what way will we identify it, so some tricks etc. have been written, relations have been done, these are some standards systems, with respect to them if PST is drawn then this PST of the dispite, that is, if there is any system, then see in what way it came directly, right? So this has been included.

[00:05:45]After this, central force motion has been explained.

[00:05:48]All the important formulas in central force, whether it is differential equation orbit or your Lagrangian, about B effect, about oscillation, minimum energy are there here. Then after this, the relation in some particular flower and all the results regarding this binary system are written here. The bireal theorem is also entered here.

[00:06:10]Got it? And after this you have these different conditions in which we can find out in which orbit the particle can move. Similarly, here is the relation regarding velocity. Then these Kepler's laws are included here.

[00:06:24]Ok? And after this, all these flowers are in circular orbit under the inverse force motion.

[00:06:28]Sorry. Then comes Ridge Body Dynamics.

[00:06:33]What is there in Rigid Body Dynamics, from all its moments of inertia to all its theorems and the product of inertia. Inertia tension was also written about here. These are two types of theorems. Then there are different types of systems or objects with respect to moment of inertia. About the Different-Different Axis. All these are included here.

[00:06:52]Next comes the pure rotation angular momentum, regarding the rigid body dynamics you were told about. It happened regarding the center of mass.

[00:06:59]Then there is a rolling case here, right? So in this way, this is a review of all the short notes regarding all the important topics that could be there in classical mechanics.

[00:07:08]If you want to purchase these, you can go to the ID I have given in starting @net dfer one and you can purchase it here.

[00:07:20]Ok? So if you feel like it, you can contact me. Rest I will put the ID meaning in the pin comment. So you can contact directly from there also.
