a while back my physics teacher attempted to teach me inclined plane problems, however he only showed me once and I understood absolutely nothing. I was hoping that some kind fellow out there might be able to help me out, either by explaining me all the possible calculations involved, involving friction and not involving friction. I have looked in some text books and they mentioned using the dot product as a means if solving these problems, however I understood very little of this. Even if somebody could just provide me with a link that explains the situation, I would greatly appreciate it.

Many thanks in advance,
