APB – Cops do math & physics at work!!!

As part of the San Diego Festival of Science and Engineering we spent an amazing 2 hours in a free workshop put on by the Escondido Police Department. The audience was a mix of homeschool families and high school students and it was standing room only…

IMG_3685The presentation was broken into two one hour sections – Traffic Accident Investigation and Forensics. Both areas were engaging and clearly demonstrated how math and science are used on an every day basis within the police force.

We learned about all of the tools that the Collision Investigation Unit use – both high tech and low tech to help decode and deconstruct the scene of an accident so they can then replicate it, both to determine cause and to demonstrate the information to others (i.e. in a court room).

We learned how to calculate velocity and what the ideal safe speed is for a car driving at night based upon visibility provided with high beams and human response times (hint… it’s around 28-30 mph).

We learned about how kinetic energy logic is used to measure the velocity of a vehicle in an accident (what goes in to a force comes out of the force with equal energy – like the balls).

And we learned how you can use math and physics to determine angle and velocity of the vehicles in a crash based upon the angles of momentum and the size of crash damage. I was blown away with how effectively the officers conveyed the information and how they managed to connect it so simply and clearly with the kids in the room!

The Robbery/Homicide team came in and ran a mock investigation of an incident with blood spatter to determine who’s story was correct between two complainants. It was a little slower paced because the group was so large and they had kids doing some of the work but there were lots of good nuggets of information.

The BEST part of the whole 2 hours was the recommendation that students get a BACHELOR’S DEGREE if they want to become police officers. It was a slam dunk for Hunter that he now needed to shift his goal from college to university – whew… THANK YOU ESCONDIDO POLICE DEPARTMENT!
