Super User HoosierHawgs Posted December 7, 2015 Author Super User Posted December 7, 2015 Haven't perused the whole post yet. Sorry about that. Anyway, this chap Galileo dropped dropped a bunch of different things (with different masses/ weights) from the top of a tower and (tried to) prove(d) that the (falling) speed is not a function of the mass. Which is easy to see if you inspect the laws of motion under Newtonian physics (constant acceleration/ v = u + ft etc). All other things being identical, the volume of a 1/2 oz jig is larger than that of a 1/4 oz jig. Buoyancy is a function of the volume, and friction is proportional to velocity, yada yada. Long time back I tried to work this deal out, mathematically, with a bunch of assumptions (of course). I forget what I actually derived, but I think it's what the consensus is. That is, a heavier jig falls faster. Not sure what pulleys and the other stuff have to do with jigs. They only fall at the same speed when their is no friction or resistance. Thusly if you put a feather and a rock into a vacuum tube they would fall at the same rate. Quote

Super User Fishing Rhino Posted December 7, 2015 Super User Posted December 7, 2015 Y'all got a problem with that theory water ain't air! Both water and air are fluids. In any case, don't include me in the Y'all. I said that water has more drag than air in a prior post. Compare the red highlighted above to this from my post. So, in addition to the weight, the shape of the weight, (Think streamlining) is a factor to be considered. The trailer acts like a parachute. It has drag when falling through the water column. Water drag is far greater than the drag created by air. Quote
Super User HoosierHawgs Posted December 7, 2015 Author Super User Posted December 7, 2015 Y'all got a problem with that theory water ain't air! Water and Air both effect what is now known in Physics as the Idea of Free fall. In Free Fall, an object does not encounter any other force besides the force of gravity. In the free fall equation, mass cancels out and two objects will fall at the same rate. But because a jig is falling through the water, it is not in free fall. Something close to free fall can be observed with two rocks in the air because the force of friction upon those rocks is infinitesimally small. Quote

Super User Choporoz Posted December 7, 2015 Super User Posted December 7, 2015 Forget physics...too many variables for me I can't get past the geometry.....ask WRB about spool size, gear ratios, IPT, line diameter, casting distance, retrieve rates....my head gets to spinning faster than a Revo Rocket 1 Quote
Super User Catt Posted December 7, 2015 Super User Posted December 7, 2015 In a vacuum, one only has the attraction force of gravity Free fall refers to the motion of objects influenced only by gravity Thus in a vacuum the steel sphere will fall at the same rate as the feather, but in a fluid (air or water) they will fall at totally different rates. 1 Quote
RAMBLER Posted December 7, 2015 Posted December 7, 2015 I've done some math when comparing the diameter (not pound test) of line to the diameter of the braid I put on a reel, so that I could come up with a semi-intelligent guess on how much backing to put on a reel compared to how much braid I wan't on that reel. As far as physics goes, I have that while fishing, too. I usually find a brushy shoreline to hide in and hang over the side of the boat and get rid of it. Quote
Super User Catt Posted December 7, 2015 Super User Posted December 7, 2015 Talking the physics of "free fall" reminds me of when I worked for Boeing on NASA's Reduced Gravity Research Aircraft, KC-135A Stratotankers known as the "Vomit Comet". Y'all wanna talk about the effects of repeatedly dropping something that big through the atmosphere, y'all should have seen the stress fractures in those x-Rays! 1 Quote
Big C Posted December 7, 2015 Posted December 7, 2015 Here's one for ya. Imagine you're in a box, the box is in space. Now in the box, in space, you are on a bassboat. In the box, in space, on the boat you are fishing. Now you can do this because, in the box, in space, on the boat, fishing for bass, you are on a lake with both peacock bass and smallmouths. Now you have that mind picture imagine a huge lever with a pulley flips the entire box upside down. Are you in the box, in space, fishing off the boat, for both peacock bass and smallmouths flipped upside down also, or since there is zero gravity in the box in space, only the box moves? Quote

Super User J Francho Posted December 7, 2015 Super User Posted December 7, 2015 Look at lever types. A rod is used as a Class 3 lever, when fighting a fish. https://en.wikipedia.org/wiki/Lever 1 Quote
Super User gulfcaptain Posted December 7, 2015 Super User Posted December 7, 2015 My thoughts exactly......Whaaaaat????? 1 Quote
Super User Sam Posted December 7, 2015 Super User Posted December 7, 2015 Yes, but in a layman's context. When selecting a rod; choosing a line for a specific application; when using different types of baits; when operating the boat and you have to make a curve in the river; when you blast off; when you slow down and approach a fishing location trying to avoid having the waves rock the boat when you get to it; and other different things that we encounter while fishing and getting ready to fish. We all go through physics without even knowing it. Great post. 3 Quote
Super User HoosierHawgs Posted December 8, 2015 Author Super User Posted December 8, 2015 Look at lever types. A rod is used as a Class 3 lever, when fighting a fish. https://en.wikipedia.org/wiki/Lever Yeah, I read up in the other physics thread I found what you said about that. Looked it up and found some stuff on it here: http://www.ohio.edu/people/williar4/html/HapEd/NASA/SimpMach/Lever.htm Judging on that description, then yeah a rod would be a third class lever with a fulcrum in the handle, the effort in the backbone, and the load on the upper/tip section.

Super User HoosierHawgs Posted December 8, 2015 Author Super User Posted December 8, 2015 I just find physics so fascinating because it is the reality we all live in. Most never thinks about how physics effects everything we do, but I see it all around me, especially after sitting in a class by the physics wizard Mr. Haiducu. Quote
Super User Senko lover Posted December 8, 2015 Super User Posted December 8, 2015 I usually try to distance my fishing and my school as far as possible.......my thoughts are typically: not doing school? Let's go fishing 2 Quote

Super User soflabasser Posted December 8, 2015 Super User Posted December 8, 2015 This weekend I used some knowledge of physics and geometry to catch a big Snook out of one of my bass spots. It was so dark it looked like a bass on Steriods! 1 Quote
Super User WRB Posted December 8, 2015 Super User Posted December 8, 2015 Yes. Riddle me this. Why would a 1/2 oz jig sink faster than a 1/4 oz jig (same trailer)?Here is a question to solve; How much does a 1/2 jig weigh in water?-or- How much does a live 10 lb bass weigh in water, more or less than a 1/2 jig?

Super User DogBone_384 Posted December 8, 2015 Super User Posted December 8, 2015 Thankfully my last Physics class was 30 years ago.... I'm OUT! Quote
Super User deep Posted December 8, 2015 Super User Posted December 8, 2015 Less than 1/2 oz weight. Subtract all forces opposing the downward fall. Bass doesn't weigh anything. Neutral buoyancy. Quote
