Question

Which of the following is true for any collision?

• A. Both linear momentum and kinetic energy are conserved
• B. Neither linear momentum nor kinetic energy may be conserved
• C. Linear momentum is always conserved, however, kinetic energy may or may not be conserved
• D. Kinetic energy is always conserved, but linear momentum may or may not be conserved

Answer 1

Answer: (C)

Kinetic energy is conserved in elastic collision but kinetic is not conserved in inelastic collisions.
So, linear momentum is conserved in ail type of collision but kinetic energy is not conserved in all type of collisions.
