Fishing contains a wide variety of physics. when you cast you are using projectile motion and rotational motion. when you hook a fish it will often use the drag from the current agenst you. Immagine draging a fish through a swift current. You deal with the tention of your line, and the friction of the line through the guides. you also deal with friction when you use a drag.


One of the key components of your fishing gear is the reel.

These are spinning reels designed for smaller fish. You would probably use a reels like this for lakes.

These reels usually have a series of gears that turn the line collecting devices several times for each crank of the handle.

The reel on the left is the simpler design. That design has a stationary spindle and a bar that rotates around it to collect the line. On most models the drag works by a screw on the top of the spindle that applies pressure on the spindle to increase or decrease the friction to allow the spindle to spin if the fish applies enough force to overcome the friction. The problem with this design is that once the fish breaks the static friction the resistance to the fish pulling out line decreases and it is very difficult to change while fighting a fish.

the closed faced reels have a small peg inside that catches the line and then spins around the top of the spindle. For this design the reel has a plate that can be moved up and down by a dial on the front. This plate is what controls the drag. The advantage of this method is that it allows you to adjust the drag while you are fishing.

This reel is designed for off shore fishing. This real is much larger and is geared so you must crank the handle several times in order to get the spindle to make a complete rotation. A handy thing if you have to haul up a fish that is 50kg or more from the bottom of the ocean. This reel works by turning the spindle while the line feeder remains stationary. The drag works by pushing a plate into the spindle. There is a knob on the side that allows you to increase the pressure on the plate.

When setting your drag you must take into account more then line strength. You must also take into account your hook and the strength of the flesh that you are probably hooking into.

The Physics of Fishing Essay

- The Physics of Fishing The use of a boat while fishing and some of the physics applicable to boating will be included in exploring the various ways physics applies to the sport of fishing. Other topics will include the fishing rod, fishing lure, casting, and the fish itself. The boat floats on the water according to Archimedes Principle which states an immersed object is buoyed up by a force equal to the weight of the fluid it displaces. The force applied downwards by earth’s gravity coupled with the upward force of buoyancy allows the boat to float....   [tags: Physics ]

Physics And Physics Of Physics Essay

- Introduction Like most sports fishing contains a wide variety of science and physics. When you cast your rod you are using both projectile motion and rotational motion. With a little luck once you catch your fish it will use the drag of the current against you. You will also deal with tension in your line. There is also friction on both the line and when you use a drag. On top of all this the force of gravity also plays a key part when casting your line. We will explore all these aspects of physics and how they make the sport of fishing possible....   [tags: Force, Classical mechanics, Mass, Friction]

Physics and Fish Bioenergetics Essays

- Welcome to the world of fish physics. Many of us understand basic fish behavior and can reach logical conclusions about where the best place to throw a fishing line is. But when we don’t think much further than that we are missing out on some very interesting details of fish behavior. We can never fully understand why we find some fish in one location and some fish in other locations until we consider the concept of fish bioenergetics. Ultimately, fish behavior is a product of bioenergetics....   [tags: physics fish bioenergetics]

Essay on Physics of Cooling Lava

- On January 23rd 1973 a new volcano unexpectedly erupted in the Vestmannaeyjar archipelago, southwest of Iceland. The new volcano was a fissure 1.25 miles long and only 1100 yards from the center of town, also named Vestmannaeyjar. The new volcano was named Heimaey. The town was mostly evacuated over the next few days and the lava slowly flowed towards town and the mouth of the harbor for the next seven months. Vestmannaeyjar is the only good harbour in that part of Iceland, and was the base for a large fishing fleet that produces a significant part of Iceland’s GNP....   [tags: physics lava volcano]

For instance if you are king fishing with 40 lb test line (approximately 18 kg) you may not want to set your drag to the line strength, because if you hook a fish on the edge of its mouth then the fish may apply enough force that the hook will actually cut through the fishes flesh.

The fishing rod is one of the basic pieces of equipment for fishing. Whether you are pulling in the big one with a deep sea pole or just catching pan fish with a cain pole a rod is a crucial tool. It is possible to hand line small fish but this method is severely limited and can be painful if you hook into a large fish.

The pole used depends on the type of fishing you are doing. For smaller fish long thin poles are used. For big fish thicker and usually shorter poles are used.

Fly rods are usually the longest. Some of them approach 3 m. While deep sea fishing poles are commonly only 1.5 m.

One of the primary functions of a pole is to aid in casting. This is important in many instances because fish are not always swimming right next to you. Casting works through a combination of projectile motion and rotational motion of the rod.

You use the length of the rod to increase the velocity of your lure. When you release your line for the cast the angular velocity of your lure becomes a projectile.

By increasing the velocity of the lure you increase its momentum.

You apply a torque to the rod causing an acceleration. The amount of acceleration is dependent on the length of the rod.

Angular acceleration equals the torque over the moment of inertia. The moment of inertia equals 1/12 mass multiplied by the length of the pole.

Since the acceleration is the change in velocity over time, the velocity of the lure is dependent on the length of the rod, the torque applied, and the period of time applied.

The most commonly used fishing line currently is monofilament, because it is cheap, light, fairly strong, and clear. The biggest problems with monofilament is that it tends to have memory problems. When the line is left on a reel for an extended period of time it tend to remain curled. This is mainly a problem for bait or drift fishing, because the line tends to hold slack.

In most instances the line is attached to a pole of some sort, but in some places people do hand line. The problem with this is it is very difficult to hold fishing line in your hand. You can wrap it around your hand but this is limited to small fish because the line is so thin that if a large fish begins to pull that force is over a small area so the pressure on your hand will get big fast.
