Exam-style question
Try this first
When would you expect to see an elastic collision?.
- A.When two cars collide in a crash
- B.When two billiard balls collide
- C.When a ball is dropped on the ground
- D.When a rubber band is stretched
Model answer
What a good answer should say
- When two billiard balls collide
Explanation
Why this works
Elastic collisions are characterized by the conservation of momentum and kinetic energy, typically seen in idealized scenarios like billiard balls colliding. The key difference from inelastic collisions is the lack of energy loss to deformation or heat.
This applies in controlled environments where external forces are minimized. Thus, the correct option reflects a common example of elastic collisions.
