Question

state and explain law of conservation of momentum​

Answer 1

Answer:

Statement

According to the law of conservation of linear momentum, for an object or system of objects, the total momentum of the system is always conserved if no external force acts on them.

The unit of kg m$s^{-1}$ and the dimensional formula is ML$T^{-1}$. The mathematical representation of the law of conservation of linear momentum is given as:

m1u1 + m2u2 = m1v1 + m2v2
