Question

After a collision, two particles move together, then the collision is?

• A. Elastic
• B. Inelastic
• C. Perfectly elastic
• D. Super-elastic

Hint:

Inelastic collisions conserve momentum but not kinetic energy. When particles move together after the collision, it is an inelastic collision.

Answer 1

The Correct Option is B

In a collision where two particles move together after impact, kinetic energy is not conserved, but momentum is conserved. This type of collision is called an inelastic collision. In a perfectly elastic collision, both kinetic energy and momentum are conserved, while in an inelastic collision, only momentum is conserved. Thus, the correct answer is Inelastic.
