Question

What are the two types of collision. Then give a brief and concise description.

Answer 1

Elastic collision: energy is conserved. In problems, use conservation of momentum. Bodies keep their shape after collision and move separately.

Inelastic collision: energy is not conserved. In problems, use conservation of momentum and energy. Bodies may stick to each other and move as one.
