Two billiard balls collide. Identify the type of collision.

Question

a
perfectly elastic
b
perfectly inelastic
c
elastic
d
inelastic

Answer 1

The collision between two billiard balls is best classified as:

c. elastic

In an elastic collision, both momentum and kinetic energy are conserved. Billiard balls are designed to bounce off each other with little to no energy loss, making their collisions elastic.
