In an isolated system, the fundamental law that governs collisions is the Law of Conservation of Momentum.
This principle states that:
The total momentum of a system before a collision is equal to the total momentum after the collision.
This is true for both:
- Elastic collisions – where both momentum and kinetic energy are conserved
- Inelastic collisions – where only momentum is conserved (kinetic energy is lost)
Now let’s briefly analyze each option:
- a) Velocity: Not conserved. Individual or even total system velocity can change due to interactions or external forces.
- b) Mass: The mass of the vehicles is constant but not the focus of conservation during the collision event.
- c) Momentum: Correct answer. Always conserved in the absence of external forces.
- d) Force: Not conserved. Forces vary during the collision and are internal/external interactions.
- e) My insurance’s premium: Humorously added — not a physical quantity.
✅ Final Answer: Momentum is the quantity that is conserved during a collision of two vehicles.
