Last weekend a few of our families got together and went to the beach to relax and go fishing—it was really fun! The fishing definitely reminded me of physics. As we cast the lines, I saw motions which resembled parabolic curves. However the patterns were not totally accurate probably because of air resistance and drag. I also thought of mass and friction because of the lead weights we added to the lines. Although we couldn’t actually see the weights and hooks underwater, the mass of the weights created friction with the sandy bottom. This frictional force was greater than the force of the current, allowing the weights to stay still. Tension was the next thing that came to mind. As the fish started to bite, I could see an increase in tension in the lines, making it hard to reel the fish in. In the end we caught a bunch of stick fish, moi, white eels, and some other cool fish. I didn’t get any pictures of our catches, but here are a couple of us at the beach…I think the black things are swans.

Must be great to have all that beach and warm weather! We're just settling in for winter here. I don't really mind, though. I love tropical islands, but after a few weeks I start to get a strange feeling, thinking it'll never snow and no one even has a coat! I guess it's 'cos that's what I'm used to...
Anyway, happy fishing!
