Per NCERT §5.11.1, an ELASTIC collision conserves which two quantities?
AMomentum and kinetic energy
BVelocity and kinetic energy
CKinetic energy only
DMomentum only
Answer & Solution
Correct answer: A. Momentum and kinetic energy
NCERT §5.11.1: in elastic collisions both linear momentum AND total KE are conserved.
