I need ideas for my physics project experiment. It has to be in the form of:

 

the effect of ____ on ____.

 

I was thinking the effect of line type and test on strength.

Maybe a modification of that to:  The effect of line diameter on strength for different compositions.  Since it can vary by brand, even just different brands of mono can have differing breaking points for the same diameter of line.  

 

Or maybe do a comprehensive testing of knot strength with commonly used line types and tests.

After the morning I had testing my new spinnerbait creations at a local lake.......I'd like to see a thesis on the effect on blade sizes and types on spinnerbait function.  Sheeesh!

The rate of applied force on knot tensile strength. For example 1" per minute verses 1" per second on equal diameter monofilament, fluorocarbon and braid lines.

This would be a good one. I feel knot strength is something that is rarely tested properly. The slow pull usually used in videos is not representative of a fast hookset. 

The physics of casting: The effects of casting a baitcaster on your rotator cuff.

 

The physics of power: The effect of setting a hook on different types and tests of line at X, Y and Z number of yards using A as the least amount of power needed to set a hook with fluorocarbon line.

 

 

In physics terms, this is referred to as "impulse"- the rate of change of momentum. The line (and/or knot) will actually break at different points according to how quickly the force is applied. Try it and see- if you know how much force can break the line, try applying the force slower or faster to show this. That's also a fair way to demonstrate the difference between mass and weight. That actually isn't a bad idea for an experiment, I like it. Good idea! A lot you can do with that one.

Maybe rod length vs casting distance and casting weight.  You could compare how a 6 foot rod is easier to cast but will give you less distance than a 9 foot rod that will cast further but will be more strenuous for the same weight lure.

 

There is a simple formula for the force a lure exerts on the angler on a long vs short rod.  Force(moment)=weight (of lure) × distance (length of rod).  The force is typically measured inn inch pounds (think torque wrench)

 

You could also use a formula for the difference in lure velocity.  Don't remember the formula, but should be easy to google.

I would go with tests that are easy to perform and also ones that you can be more confident of the results for.  To me, casting distance between different lure weights and types (spinner =more drag, lipless = better aerodynamics) is a straightforward test that offers results you can be more confident in after several tests.   You could also test the same lure with different rod lengths to see performance differences there.  Another factor could be m vs mh for different lure weights.

The effect of the bait monkey on my wallet

 

But seriously, how about the effect of various plastic bait profiles on the rate of fall? Water displacement vs density / volume / mass of the bait? 

 

Not a science guy, but I love me some mythbusters. 

 

 

The effect of friction on fishing line during the cast. Will its influence be significant in whether a line will cast well or poorly, or will its be the negligible.
