Question

while playing pool, emma notices that the pool balls bounce apart. what type of collision is this? elastic, inelastic, force, explosive

Explanation:

In collisions, elastic collisions are defined as interactions where kinetic energy is conserved, and the objects bounce apart without permanent deformation. Pool balls bouncing apart matches this description, as they retain their shape and move separately after impact. Inelastic collisions involve objects sticking together or deforming, force is not a collision type, and explosive collisions are a subset of inelastic where energy is released.

Answer:

Elastic
