What I did this weekend...>_O

Yeah...As you can probably tell by this picture, this weekend wasn't a very good one for me. I was driving and this hideous mess happened...JUST KIDDING! Haha. I'd get murdered if this happened while I was behind the wheel. This is actually my mom's friend's car. He got into a little fender-bender with a couple other cars. Someone rear-ended him and pushed his car into the car in front while sitting in traffic. Fortunately, he was unscathed, and he still ended up going to work (talk about dedication!).

The front of this car demonstrates a concept straight out of the textbook. We learned that the fronts of cars are designed to crunch like that, in order to prolong the time of impact, even though this is just a tiny crunch, it still has the same concept. Momentum is mass times velocity. Net force equals change in momentum over change in time. If the time is increased, but the change in momentum stays the same, the net force decreases, thus lessening the force of impact when the driver feels it, which is kind of the point of the crunch-able front of cars.

Imagine what could have happened if cars didn't crunch like that! :O
