These are pictures from my trip to Alaska this past summer when my family and I went halibut fishing. Fishing actually has a lot to do with physics. Casting is a projectile motion because it invovles horizontal and vertical motion. As the line is cast out, the vertical motion of the lure's acceleration is affected by gravity. The length of the rod also affects the velocity and acceleration of the lure. Even the tension and friction of a fishing pole's reel become invovled in reeling in a fish. For halibut fishing, however, we mostly just dropped our lines off the side of the boat so the bait would sink to the bottom. For this action, instead of being a projectile motion, it involves free fall acceleration because the lure just drops down vertically.

Very cool... halibut fishing and physics! Who could've guessed?
Excellent discussion, Jacy. Only one clarification, which may seem obvious and is probably what you meant: The dropped lure doesn't experience "free-fall" acceleration while sinking in the water. Only while in mid-air.
Love the pictures.
