Per NCERT §5.11.1, in an INELASTIC collision, which quantity is conserved (and which is not)?
AMomentum yes, KE no
BNeither conserved
CBoth conserved
DKE yes, momentum no
Answer & Solution
Correct answer: A. Momentum yes, KE no
NCERT §5.11.1: momentum conserved always (isolated system); some KE lost to heat / sound / deformation.
