The explosion of explosive material is application of
Correct answer: C. Law of conservation of momentum
- A. Law of conservation of energy
- B. Law of conservation of mass
- C. Law of conservation of momentum
- D. Newton's third law of motion
Explanation
This is due to the fact that momentum is conserved for all interactions, including collisions and explosions. However, kinetic energy is only preserved in elastic interactions, which an explosion is most obviously not. An explosion maintains the Law of Conservation of Momentum.

About Linear Momentum
Linear momentum is the vector product of mass and velocity, p = mv, and changes when a net external force acts. Work includes impulse as the change in momentum, conservation of momentum in isolated systems, collisions and explosions, and the distinction between elastic, inelastic and perfectly inelastic collisions.
