I took three times for each trial and averaged them out. For the radius I measured to a tenth of a centimeter, so its 6.0E-2 cm.

The radius is 0.060m, height is 0.98 m, displacement of the ring is 1.16 m, and the time is 0.860.

Wow, this book that I'm using, The Laws of Physics by Milton A. Rothman told me that to calculate angular velocity, you multiply v by r. Now I have to redo my analysis and graphs. Thanks a lot man, you really saved me.

I've conducted the experiment, and all seems well, but then I encountered a problem with the conservation of energy part. Gravitational potential energy = Linear Kinetic Energy + Rotational kinetic energy mgh = 1/2mv2 + 1/2Iω2 m= 0.598kg h=0.98m v=1.35m/s I=2.15E-3 and ω=8.10E-2 I get...

Wow, I totally passed over that the torque should be remaining constant, if my hypothesis is correct, and moment of inertia is inversely proportional to angular acceleration. It look like I would just be able to calculate the torque using any of the trials, and use that as my theoretical value...

Yeah, I wrote that moment of inertia can be thought of as the resistance an object has to angular acceleration, so naturally, as the moment of inertia increases, the subsequent angular acceleration of the object would decrease, proportional to the moment of inertia. Now this may be kind of...

Yeah, I just realized while reading what you typed that it didn't make much sense. I have now decided to make my hypothesis mass is inversely proportional to angular acceleration. Would that produce a straight line? I'd assume so, if it's anything like translational kinetic energy. Would I...

Thanks for the reply! Do I really need to include translational energy if all I'm testing is the relationship between angular velocity and mass? Will it change the angular velocity? I am adding the 3/4 ounce fishweights on the inside of the ring. I am aware that it will change the radius...

1. I'm doing an experiment where I have a brass hollow cylinder, and I roll it down an inclined plane, and after each trial, I add fish weights to the inside of it to increase the mass. I'm testing the proportionality between mass and angular velocity, with my hypothesis being an inverse...
