Q. During a collision between two bodies, which quantity is always conserved?

दो पिंडों के बीच टक्कर के दौरान कौन सी मात्रा सदैव संरक्षित रहती है?

A
Kinetic energy
गतिज ऊर्जा
B
Potential energy
संभावित ऊर्जा
C
Linear momentum
रेखीय संवेग
D
Mechanical energy
मेकेनिकल ऊर्जा

Explanation

In all types of collisions (elastic or inelastic), linear momentum is always conserved. Kinetic energy is conserved only in elastic collisions, but not in inelastic collisions.
