Question

Which of the following may no be conserved for an isolated system

• A. Energy
• B. Potential energy
• C. Mechanical energy
• D. Kinetic energy

Answer 1

Answer: (B), (C), (D)

The correct options are
B Potential energy
C Mechanical energy
D Kinetic energy

In an isolated system only $T.E$ is conserved $M.E$ can not be conserved in case of inelastic collision$.$ Some energy is converted into heat$.$ and sum of $P.E,K.E$ and lost energy remains const$.$

Hence,

option $b,c,d$ is correct answer.
