Question

Conservation of momentum

​

Answer 1

$\huge\star\:\:{\orange{\underline{\pink{\mathbf{Answer}}}}}$

➮The total momentum of an isolated system is conserved.

➮Isolated system → net external force on the system is zero.

➮Example: Collision of 2 balls A and B

Answer 2

One of the most powerful laws in physics is the law of momentum conservation. ... For a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision.
