Chapter : Physics 1st paper Chapter 4

This Video we Talked about Momentum Conservation Formula ( ভরবেগের সংরক্ষণ সূত্র & এর গানিতিক সমস্যা সমাধান) for HSC & Admission. We also have seen a special Case In 2 Dimension collision.

Newtonian mechanics is based on application of Newton’s Laws of motion which assume that the concepts of distance, time, and mass, are absolute, that is, motion is in an inertial frame. The Newtonian idea of the complete separation of space and time, and the concept of the absoluteness of time, are violated by the Theory of Relativity as discussed in chapter 16. However, for most practical applications, relativistic effects are negligible and Newtonian mechanics is an adequate description at low velocities.
