This picture shows the area where you turn from Annacis island crossing system highway towards Highway 99 in Mud Bay in British Columbia. My mother, brother and I always cross this place coming home to South Surrey from our daily Saturday voyage to Vancouver. This turn has made my isolation in the seat of an automobile for a long period of time somewhat bearable. I had always been fascinated by what I now know as centripetal acceleration. Always on the turn I would feel my body pressed against the door as if I was going to be thrown out. I would be amused by objects sliding on the back dash board. Until I took my first courses in physics I could never explain the phenomenon which had always caught my attention.

My physics teacher, Mr. Quan, has taught me that I am experiencing the effect of changing velocities despite my thought that it was some sort of outward force. I also learned that on turns similar to my photo that roads are tilted at an angle to enable one to turn at speed.

In conclusion, I have become a little wiser by knowing more of the secrets of the natural world about us.
