I am currently working on my physics extended essay for IB and I have chosen to investigate how the amount of water in a cylinder affects its motion down an inclined plane. I am planning to carry out an experiment by varying the amount of water in a can and measuring its velocity down an incline.
Do you have any suggestions on how I would be able to calculate the rotational inertia of the can for each trial using data for its velocity? What are some other variables that I would be able to measure?
This is my first time posting here, so please let me know if you would like more details about my question. Thank you so much for your help!
