Beta, main in cheezon ko apni gym ke dumbbell aur cycle ke pahiyon se samjha sakta hoon. Rotational motion woh hai jaise pahiya ghoomta hai, moment of inertia bataata hai ki use ghumana kitna mushkil hoga, torque woh jhatka hai jo ghumaata hai, aur angular momentum... wahin main phas gaya tha. Isliye aaj tak mere purane engine ka wo vibrating issue theek nahi kar paya, jabki degree haath mein thi.
