Here is my new data set. I actually had to redo tracking once more in Tracker due to scaling issues. I also discovered that Tracker provides data for kinetic energy and ω, so I used ω and the linear velocity tracker provided to determine that the ball's radius is about 0.035 meters (we weren't...

Velocity was given, but I am unsure whether it is truly calculating the correct velocity, as the numbers seemed high, so I will try it myself.

Alright, so would ω take the place of a variable in the linear KE equation, or is it just an added term to account for the rotational motion of the ball? Also, I'm assuming to calculate for v, I would do something along the lines of KEi + PEi = KEf + PEf and solve that out? I think what truly...

These are my new numbers for potential energy. Should I be using the form of KE = 1/2Iω2?

Well, I am aware that friction is affected the velocity of the ball. Should I also be calculating friction to obtain the kinetic energy? Our lab states to just use 1/2mv2, so I wasn't too worried about friction. The velocity is being measured through Tracker, but like I said, I don't believe...

If there is another term, I am sorely ignorant as to what it may be. I can think of a few other variables related to the problem but I'm not sure which one would effect kinetic energy.

Hi guys, currently trying to figure out part of my lab for Physics I. We used the program Tracker to gather information on a metal ball rolling down a metal track and through a loop. The origin was set at the bottom perpendicular to the top of the angled track where x and y = 0. Here is the data...
