During inelastic collision of two particles

Options

  1. A( KE )_ final =( KE )_ initial
  2. B( KE )_ final must be greater than ( KE )_ initial
  3. C( KE )_ final must be less than ( KE )_ initial
  4. D( KE )_ final must be greater or less than ( KE )_ initial

Correct answer

B. ( KE )_ final must be greater than ( KE )_ initial

Step-by-step solution

During inelastic collision of two particles kinetic energy after collision is not equal to kinetic energy before collision. Here, KE appears in other forms. In some cases, (KE) final .^ (K E )_ initial such as when initial KE is converted into internal energy of the product (as heat, elastic or excitation energy) while in other cases ( KE )_ final ( KE )_ initial such as when internal energy stored in the colliding particles is released.
