I have taken classes long time a ago in the US, my instructor never explained it this easy. Please keep up creating more of these such helpful lectures. Thanks
Dear sir @5:28 in free vibrations you applied d alemberts principle for that, why dont we apply that here ? shouldn't we consider acceleration here ? how to know when to consider and not to consider acceleration clarify sir plzz
Sir, In newtons method, you have stretched at some distance x , so you told the force act on the mass by spring is -kx. But, In energy approach, you virtually stretched some infinitesimally small distance ∆r , it could be, the force by spring, -k ∆r. How it could -kx. This is my doubt, i don't know, it may be a totally wrong question....
Hello and sorry for replying late, When we are doing energy approach, we actually disturbing our system from its equilibrium state, means at this moment, the spring is stretched. So if you give del_r displacement actually the spring is now having a total change in length is (x+del_r), but as del_r is infinitesimal small so we assume the spring force still kx and then we say the work done by spring force is k.x.del_r. if still I could not answer your query, let me know I will try to explain it in other way.
amazing teacher
very good woodwork in explaining the fundamentals. Thank you!!
thank you!! very helpful and easy to understand!!
You are just awesome , the way u explained everything , I am loving it : )

how to know when to consider and not to consider acceleration
clarify sir plzz
Excellent lecture. The next one too.
Thank you
That is an awesome exolaination
Excellent 👌

felt bad for your finger ,sir
Bhaiya mechanics ka exam hai maine padha hai hai aapke channel se lekim time bht kmm tha isiliye ache se nhi padh paya thora help krr do exam me plzz
In what way need my help
