Q. Which of the following is true for inelastic collisions?

बेलोचदार टकरावों के लिए निम्नलिखित में से कौन सा सत्य है?

A
Momentum is not conserved
गति संरक्षित नहीं है
B
Kinetic energy is conserved
गतिज ऊर्जा संरक्षित रहती है
C
Momentum is conserved
गति संरक्षित है
D
Mass is not conserved
द्रव्यमान संरक्षित नहीं है

Explanation

In inelastic collisions, momentum is always conserved (as per Newton's laws), but kinetic energy is not—some of it is converted into other forms like heat, sound, or deformation.
Mass is also conserved unless nuclear or relativistic effects are involved.
