Question

Which of the following is NOT correct about momentum conservation?
Options
A In an explosion, total momentum before explosion is zero
B During elastic collision, colliding objects always separate after collision
C During inelastic collisions, objects stick together after collision.
D Total kinetic energy is conserved during inelastic collision.
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

In an inelastic collision, kinetic energy is not conserved; it is converted to other forms. Momentum is conserved in all collisions if no external forces act. Statement D is incorrect.

Hint

Kinetic energy is conserved only in elastic collisions.
