    Rolling a ball down an inclined slope. Something's wrong.

    Uhh, to be completely honest, I have not studied anything you guys have mentioned. So yeh I'm a complete noob in physics. Its only an optional extension in our independent research project.

    Uhmmm, no I'm in Year 9 in a selective high school in Sydney Australia, so maybe class 9? I don't know.

    Oh. But the cylinder here is rotating. Does that mean I have to use another formula regarding this project? :((

    Thank you again for your reply. After searching the internet, it said that the coefficient of Friction (u) regarding plastic on wood, was 0.5 and 0.4. Do i just substitute these values in the formula that you provided me with in your first response? And no I haven't read the chapter Laws of...

    Thank you very much for your reply. I see that I'm missing friction. So how would i find out the friction between the gluestick and inclined plane? I didn't really understand the last few sentences when you mentioned the formula's relating to friction and acceleration. *edit. OK I understand...

    Hi guys, Homework Statement I'm trying to find the theoretical time it takes for a glue stick to roll down an inclined plane of 10 degrees. We then have to compare it to the practical value, which was 1.09 secs.(Average over 10 repetitions). The glue stick has a mass of 10g. The distance of...
