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 ______؟
A. Retains more momentum
B. None of the above is true
C. Losses some momentum
D. Remains constant
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.
