waikiki

I was at waikiki this weekend and as I was taking pictures of people walking on the street I noticed that the image of the cars looked really interesting. It's kind of dark so only the lights are really noticeable. Since the cars were in motion, they had kinetic energy (.5mvsquared), and since they were probably accelerating (change in velocity or direction), they also had work (change in kinetic energy) and power (change in work over time). The motor in the car is doing the work to make the car accelerate and gain kinetic energy. Even a simple thing like a car driving involves the majority of the lessons we have learned so far. If there was a collision (although I wouldn't hope to see one) then that would have involved the latest chapter we covered. I seem to notice physics in places where there are cars...
