Looking through old photos...Tada! A parasailer hanging out near the Superferry! I'm a little sad about the Superferry leaving (since my family also had free roundtrip tickets) but when the Superferry WAS running I snapped this photo on the way back from Maui. This parasailer doesn't fall at -9.8 meters per second, thanks to wind power! Looking at this photo now, I was reminded of our graphs on displacement, velocity and acceleration. However, if there was a stationary motion sensor watching the parasailer, I think the corresponding graph would look pretty strange! Even if the Superferry was being measured by the motion sensor, it could move out of the path. The parasailer could also change its velocity (direction and speed) by adjusting the shape and orientation of the parachute. The Superferry also has its own set of physics! it gets propelled forward by water jets that shoot water in the opposite direction. Action reaction! Though we haven't learned that yet. :] That's all for today, but I'm sure I'll be learning a lot more physics for future posts!
