Hi Vikas ,

I understand that you want to get N.V. Sir ( Nitin Vijay ) who teach Physics in Motion Classes Kota but you can not get the videos link as they are copyrighted and have a very low chance that you may find them online

You may need to buy them online from Etoos India where you may get all his lectures after you purchase them and i am attaching the link for the same : https://www.etoosindia.com/faculties/jee/physics/85/n/detail.do
