forensics? (Score 1)

I'm surprised no one has suggested forensics yet. If you're not able to get the students into an actual lab, its a great way to keep them interested in a physics problem:
- given a ballistic pattern of a bullet OR
- given a blood splatter pattern OR
- a fall OR
- from a position of a body:
determine trajectories, velocities, etc. and likelihood a death is suicide or homicide.

- use momentum to analyze a car crash, or any force-related accident, and reconstruct it.

CSI is popular partly because of physics.
