Law of conservation of momentum defines that the total momentum of a system of two bodies before and after collision ______?

رفتار کے تحفظ کا قانون اس بات کی وضاحت کرتا ہے کہ تصادم سے پہلے اور بعد میں دو اجسام کے نظام کی کل رفتار ______؟

Remains constant

Retains more momentum

Losses some momentum

None of the above is true

Explanation

The law of conservation of momentum states that the total momentum of a closed system (such as a system of two bodies) remains constant over time, as long as there are no external forces acting on the system.

This means that the total momentum before a collision is equal to the total momentum after the collision.
