# The Physics of Fishing Essay

857 Words 4 Pages
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. The boat consists of separate components each having their own center of mass, or center of gravity. The boat, the occupant(s), the engine or oars, and the fishing gear all combine to …show more content…
The length of the fishing rod directly relates to the velocity, momentum, and distance that the lure can be cast. A longer rod can cast a lure at a greater velocity and a greater distance. The inertia of your lure, when casting overcomes the drag of your line, which is negligible, as it comes out of the reel and through the guides at the point of release. When the line is released for the cast the angular velocity of your lure becomes a projectile. Increasing the velocity of the lure increases its momentum. Torque applied to the fishing rod causes acceleration. The amount of acceleration is also dependent on the length of the rod. Again, a longer rod will cause greater acceleration. 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. 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 the cast lure is in motion.. The bent fishing rod contains potential energy caused by increasing the tension in the fishing line. Potential energy is present and a force is exerted on the fishing line. Potential Energy Force PE = (1/2)kx2 F = kx
