    I like your teaching of physics. Could you cover problems from various aspects of physics with an aim to perfect mechanical comprehension. Improving mechanical comprehension through problem solving in physics would be a huge motivation to contnually learn physics. This approach would stick physics principles in mind and prompt the mind to question what why where how and reach the right conclusion. Thanks

For thinkers the number is 123 which I liked and made for his video. I am an IIT JEE aspirant and these problems I did in my first basic paper solving of nlm for pulley mass systems during my preparation. Edited to say thank you for helping me refresh and revise a bit. I am still preparing and hope to get selected the next time. Please pray for me😊
